Keychain Puzzles

any novelty keychain fobs and charms are available and can be considered collectible - one can find scores of different designs, both modern and some decades old. Among them are a variety of keychain puzzles (or key chain puzzles) - the subject of this section.

Keychain puzzles include interlocking, twisty, sliding piece, dexterity, and other types. Their most important characteristic is being small - according to experts three inches or less in the longest dimension (and even that is pushing it). Even when no chain or cord is included, often there is a hole or a loop where one could be attached.

In this section, I have focused on the interlocking variety of keychain puzzles though I do show some other types I've collected. Most collectors of keychain puzzles will admit certain small interlocking constructions into their collections even when the puzzles were not really intended to be hung on a keychain - I have included some examples here. They are referred to as "Miniature Plastic Interlocking Puzzles" and many were produced in Japan.

In addition, some keychain "puzzles" either are very simple - consisting of only two pieces - or don't interlock but rather press together. Such items are in a controversial gray area on the periphery of proper keychain puzzles. But of course part of the fun of collecting is to define one's own boundaries. I have included a section for "Gray Area and Non-Puzzle Keychains." I don't collect non-puzzle keychains but I sometimes acquire them as part of a grouping. A few of them are worth illustrating either because of their novelty, or because they embody a clever mechanism, or because I have seen them confused with puzzles and can provide clarification.

I have organized the keychains shown in this section into several categories
(you can mouse over and click on the entries in the menu box below):

Below is a showcase of thumbnails of most of the types of keychain puzzles I have found.

  • Guided by Dundas (see below), I have highlighted like this about 70 puzzles that probably belong in any basic collection. The focus is on puzzles issued in the U.S. in the 40's and 50's, many by Lional and Lido.
  • I have highlighted like this another 30 or so puzzles an avid collector should be able to obtain - some from Hong Kong, England, France, or Germany.
  • Many of the rest are from Europe or Japan and may be comparatively rare. What I have experienced to be the rarest, I have highlighted like this.

Small, intricate and colorful plastic keychain puzzles were sold beginning in the 1940's by American manufacturers or brands such as Helenhart Novelty, Plas-Trix, Toy Trix, Pal Plastics, Chemtoy, Harrison, Lional, Lido, and Mechanical Servants. In the UK they appeared under brands such as Peter Pan, Randall or Merit, Roddy, and Bell, and in Germany under the Pussy or Pussycat brand. Several interesting designs were issued in France, Japan, and others in eastern Europe. Some interlocking keychain puzzles - spheres, cubes, elephants, and pigs for example - are still made today in Hong Kong.

The puzzles, aimed at impulse buyers and sold for pocket change, were usually displayed in stores on large cards from which several puzzles - usually of the same type but occasionally a variety - were hung by their chains. Each puzzle would be accompanied by a small solution sheet - taken at sale time from a stack stapled to the display card. Some of the old larger store display cards can still be found - a few examples are shown here.

Sometimes individual puzzles were accompanied by an attractive heavier printed card, or packaged in small bags - either assembled or in pieces - or appeared in boxed sets or blister packs. Most often today they're found loose and without a card or instruction sheet, so it is always nice to be able to acquire an original card or solution sheet along with a vintage keychain puzzle. Shown below are some example cards and solution sheets.

Using Google Books search, I have been able to find several notices for wholesale lots of keychain puzzles dating from the late 1940's and early 1950's, in Billboard magazine. An example is shown at left, clipped from the May 28, 1949 issue of Billboard.

A determined collector should be able to find dozens, if not hundreds, of intact examples of vintage plastic interlocking keychain puzzles, and collecting such puzzles has the advantage of requiring a minimum of storage space! While the typical puzzle has only six pieces, and many of the puzzles share an internal architecture derived from one of a few common recurring designs, some of the interlocking designs can be unexpectedly challenging and pleasingly clever.

I am aware of very few published articles concerning keychain puzzles, and until recently the 1998 book Toys That Shoot and Other Neat Stuff by James Dundas was the only real reference showing a large variety of interlocking keychain puzzles (AFAIK). The book has a section on keychain puzzles on pages 70 through 80. Dundas shows about 70 puzzles and suggests rarity and dollar values for them - but the valuations given by Dundas are no longer considered accurate. Collector Steve Butler has written a few articles on keychain puzzles - one article entitled "It's a Puzzle" appeared in the September/October 1991 issue of The Toy Collector magazine. Another two-part article "Key Chain Puzzles" appeared in Antique Toy World in April and May 2004. A third article entitled "Puzzles and Their Place" appeared in the August 2015 issue.

In 2011, Jerry Slocum and William Waite issued their Compendium of Keychain Puzzles, which gives details for 465 puzzles (467 according to the internal numbering but there are unassigned numbers). The Compendium has been updated to a 2nd edition as of August 2015 and now contains 558 puzzles according to the internal numbering. Several from the 2011 1st edition have been reclassified or renamed, or dropped as it was decided they don't really qualify well. Unfortunately the assigned numbers have changed from the 1st to the 2nd edition.

In the U.K. several of what we in the U.S. know as "keychain puzzles" are known as "Jig Toys" and have been issued as cereal box premiums. I like the idea of thinking about these puzzles as miniature "jigsaw toys" - the best designs seem to me, while not exactly having the traditional curvy tabs and notches of a jigsaw, to have pieces that interlock along non-obvious borders. You can read more about Jig Toys at Hugh Walter's Small Scale World blog, in his post entitled "Jig Toys - Puzzle Key Chains." There is also a website called Cereal Offers that aims to document all U.K. cereal promotions over the years. That site has nice pages about Jig Toys free in Corn Flakes in 1959, in Sugar Smacks in 1960, in Frosties in 1960, and in Frosties in 1970. The website has numerous photos including pictures of the boxes, puzzles (many on sprues), and instructions.

Most of the Jig Toys were issued in soft plastic, and the designs which appeared as cereal premiums starting in 1959 - the Jeep, Covered Wagon, Helicopter, Aeroplane (equals Merit's Jet Fighter), Liner, and Transport Lorry, had been issued by J & L Randall Ltd. in their Merit line in hard plastic in 1954, or by Bell (the Liner equals Bell's Steamboat). In 1970, the Lorry, Plane, and Helicopter were replaced by a Tractor (the David Brown design but with a nearly non-existent exhaust stack), a Sedan (the Mechanical Servants design), and a Horse (the Dutch design). The Horse is almost always found without its tiny ears piece. The Liner was replaced by the Destroyer, and though the Covered Wagon remained, it underwent subtle design changes.

Keychain puzzles have inspired art - Steve Armstrong created a series of wooden sculptures - scaled-up renderings of classic keychain puzzles. They were on display at the Aron Packer Gallery in Chicago.

カバヤビッグリーグガムパズル (means Kabaya Big League Gum Puzzle) - Kabaya Foods Corporation is a Tokyo-based confectionery company founded in 1946. Originally manufacturing caramel, in 1963 they began producing gum and chocolate. Over time, Kabaya has issued a wide variety of small plastic toys and puzzles as "extras" or "bonus" items to accompany their candy or gum products. See for example The Transformers Wiki entry on Kabaya.

The company Leaf was founded in the 1940s when it was also a confectionery manufacturer. The Leaf brand name is associated with trading cards - according to the website The Cardboard Connection, Leaf produced one of the most iconic postwar vintage sets, 1948-49 Leaf Baseball, which featured the rookie card of Jackie Robinson. (Note that the current Leaf Trading Cards founded in 2010 has no connection to the gum and card manufacturer of the 1940s.)

Kabaya and Leaf entered into a partnership and in 1967 issued Kabaya-Leaf baseball cards - see the Japanese Baseball Cards blog. At some point they also produced Big League chewing gum.

Starting in the 1960's, Kabaya issued dozens of small interlocking puzzles in both soft or hard plastic to accompany their Big League Chewing Gum. The Kabaya-Leaf company issued over 100 puzzles including 40 puzzle kun (the set of 40 is fairly rare, having been issued only for a short time in the early 1980's) and over 60 in the Big League Chewing gum series.

Glico (sometimes mis-spelled Glyco) is another Japanese confectionery company that issued many small extra or bonus toys with their candy products - but few if any true puzzles.

I began collecting keychain puzzles in 2011, after I acquired a "Wha Hoppen" in March - although as a child I had a small white Bibendum keychain puzzle I received as a souvenir of the New York Auto Show I used to attend with my father.


Here's my collection of keychain puzzles:

The First Keychain Puzzles
These are examples of the Trylon Perisphere puzzle souvenir from the 1939 New York World's Fair, issued by the Helenhart Novelty Company. It is very small, and it is said (see Slocum) that this is the puzzle that gave birth to keychain puzzles (even though it has no chain).

The Trylon Perisphere puzzle is made from a very early form of plastic and often the pieces have warped. One piece in particular seems susceptible to damage - in the group of orange pieces shown above, it is the bottom piece and is broken in two. You should not soak these pieces in water!

I found an intact example of the orange sphere / blue Trylon version, shown below.
In each Trylon Perisphere puzzle, the six letters W-H-A-L-E-N are embossed, one in each of the six pieces.
Grover Whalen was president of the New York World Fair Corporation, and helped run the 1939 fair.

Here is an original instruction sheet that came in the box with the puzzle:

Irving Steinhardt received patent 2178190 in March 1939 for a six-piece interlocking puzzle. The patent depicts a spherical puzzle with an obelisk through it, but notes that the outside shape can vary. The drawings also include a bottle shape. The sphere pieces shown in the patent match the pieces of this puzzle. Steinhardt's design patent D112470 of Dec. 1938 clearly shows the Trylon Perisphere design, and is cited on the puzzle box. Steinhardt also received design patent D118253 in Dec. 1939 for an egg-shaped interlocking puzzle. Steinhardt has many puzzle patents.

The Trylon Perisphere souvenir puzzle appeared in metal as well, in both large and small sizes - although I am not sure that these aren't one-offs since I don't know their provenance, but I have seen one before on a popular auction website.

The Trylon Perisphere souvenir puzzle in metal - larger size.

The Trylon Perisphere souvenir puzzle in metal - smaller size.


This Mystery Ball Puzzle contains virtually the same pieces as the Trylon Perisphere, except the Trylon key piece has been truncated and become part of the ball.
According to Slocum and Waite, this is the first keychain puzzle, issued by the Helenhart Novelty Company of New York City.  

I found an example with its original card - it was evidently sold at F.W. Woolworth.
This puzzle must have been produced in large quantities because many surviving examples can be found, with a variety of attachment types...

The Ball's pieces also have the letters W-H-A-L-E-N inside.

The patent number 2178190 is embossed on the hollow inside of the key piece.

Steinhardt also patented the horseshoe-shaped clip, in 1942 (D132116), and another type of retention device having a cord, in 1944 (2361069).


I found this clear or translucent example of the Mystery Ball. The pieces contain the WHALEN letters and the patent number.

Other Steinhardt Architecture Puzzles
Here is a version of the Steinhardt Ball from "Peter Pan" made in England, with its card:

Here is a version of the Steinhardt Ball from Germany, with its card:

NOTE the clever two-piece construction of the key piece - this allows it to be removed from the puzzle without having to detach the chain.
The horseshoe clip proffers the traditional English "Good Luck."
Also note these piece have no WHALEN lettering, nor any patent number on them, but the ball is the same size as the Helenhart product.
The pieces are very precisely made and fit is excellent.

The Steinhardt configuration in ball form is still made today in China.

Here is a set of eight colorful keychain puzzles, obtained in 2018 from China.
All use the Steinhardt architecture.

A large version of the Steinhardt ball - hard plastic

A large (45mm) version of the Steinhardt Ball, with hollowed pieces - Hong Kong

A farily large version of the Steinhardt configuration in ball form has been used in France to advertise Air France and Pampryl.
Pampryl is an orange drink.
I believe both the Air France and the Pampryl versions were made from the same molds,
as in both cases the surface of the sphere has embossed "continent" outlines on it.

I have two Air France keychain ball puzzles, and they are of different sizes.
Also received a copy of an insert that seems to have accompanied the Air France puzzle. Note that what the insert says is incorrect! The "game" was not invented by the Japanese - as we know, this puzzle topology was invented by Steinhardt! And of course there are six pieces, not five.

This large version of the Steinhardt Ball was issued as advertising for Bennes Marrel.

The Steinhardt configuration in ball form appeared as the Sputnik.
According to my source, this was issued by Sumugam of India in 1988.

Here is a comparison of Steinhardt Ball puzzle sizes.
From front to back, left to right, balls and sizes are:
Bowling Ball - 20mm, Steinhardt Ball - 22mm, soft KL ball - 23mm, hard Japan ball - 24mm, hard HK ball - 31mm,
hard colored ball - 35mm, Bennes Marrel - 37mm, Pampryl - 37mm,
small Air France - 37mm, large Air France - 42mm

The Steinhardt configuration in cube form has appeared in the past in small and larger sizes, and is still made today in Hong Kong.
Here are ten examples in different sizes - one vintage medium-sized version is shown disassembled in the big photo.
The left two in the big photo are modern Hong Kong versions - one with loop and one without - and the HK pieces are shown in the next photo.
In the next photo, of two cubes, the larger cube is the same size as the HK cubes but it is stamped China. Its pieces are thin-walled cheap plastic.
The last two photos show a bagged cube, issued by the Czech company Druopta in 1983.

This 45mm Steinhardt Cube came from Hungary.
It fits together very nicely - I like it a lot.
It's not a keychain puzzle, but you can see that the Steinhardt architecture has been widely copied.

Here is a proper keychain-sized example of the blocky Czech Steinhardt cube puzzle.

Kabaya Leaf of Japan issued a Steinhardt Ball and a Cube in soft plastic

Kabaya Leaf of Japan also issued a hard plastic Steinhardt Cube.

A group of Steinhardt architecture puzzles in soft plastic from Kabaya Leaf Japan.
Only two are not Steinhardt - can you tell which?

Mechanical Servants issued a small Steinhardt Cube

Tamaki of Japan issued this boxed Die Cube using the Steinhardt Architecture

Tamaki of Japan also issued this boxed pastel/crystal Cube using the Steinhardt Architecture - they call it "Puzzle Square"
Three examples.

The Steinhardt configuration in Drop or Droplet form has been issued in hard plastic, from HK and Japan, and possibly elsewhere.
Here are several examples - note the differing chain attachments.

Kawada of Japan issued this boxed Droplet puzzle using the Steinhardt Architecture

This soft plastic version of the Droplet is from Kabaya-Leaf of Japan.

Here is a comparison of a hard plastic drop (on the left) with a soft plastic drop.
The hard plastic drop is slightly larger at 30mm x 20mm versus 28mm x 17mm for the soft.

Here is the Kun version of the drop. It is much larger than either the hard or soft version of the regular drop puzzle.

A set of four card suits from Kabaya Leaf of Japan - Club, Spade, Heart, Diamond. Soft Plastic.
All are sculpted instances of the Steinhardt configuration.

I found additional examples of the Card Suit puzzles:

Another interesting variation on the Steinhardt Cube construction, from Kabaya of Japan, in soft plastic - this is a Cube on a Diagonal:

A Crystal-shaped puzzle from Kabaya of Japan. Hard plastic.
With original box.

Several pieces resemble crossbows to me - so I call this the "Crossbow Sphere."
Not in the Compendium 2nd Ed. so far as I can tell.

5 piece Ball - Japan

Keychain Kumiki Ball

Keychain Kumiki Cube

I know this as the "Frankfort Cube" - eight examples, the first two in hard plastic and the green, blue, yellow instance in soft plastic.
It has been used for advertising in France.
This design has a kind of "hinged" clip that swings out.
I have instructions from the German company Pussycat.

Allsides Cube keychain puzzle - designed by William Waite
Mine is #16, from a limited edition of 26 puzzles. Includes a signed card reminiscent of the way keychain puzzles were sold in the 50s.
Each of the four pieces touches all sides of the cube, hence the name. Four moves to remove the first piece. "One of the most difficult keychain puzzles ever produced."

Keychain Barrel or Cylinder included in Japanese candy - soft plastic - Kabaya Leaf Japan

I found several - perhaps this puzzle was produced and/or purchased and saved in large numbers (but it still is not overly easy to obtain outside Japan):

Kabaya Leaf Kun series "Cylinder 2" #539 on p. 90 of the Compendium 2nd Ed.

Keychain Cross included in Japanese candy - soft plastic - Kabaya Leaf Japan
Was available in different color combinations:

I also found one (from Japan) in yellow and white:

This is the Kun version of the Cross Burr - Kabaya Leaf Japan

Capsule - Kabaya Leaf Japan

This is the "Kun" version of the Capsule puzzle issued by Kabaya Leaf Japan

Kun Hemisphere - Kabaya Leaf Japan

Checkerboard Brick (or Pylon) - Kabaya Leaf Japan

It was not obvious to me at first, but this puzzle has been issued in multiple color schemes -
I have examples with a white cross, an orange cross, a blue cross, and a yellow cross at both ends.
Perhaps other combinations were officially issued.
You can see both orange and white complete piece sets below.

Of course, once one has various piece sets, one can create different color combinations. However, those I show here I obtained as shown - I have not gotten creative on my own.

I also found one in yellow and white:

Here is the pair of white and yellow KL puzzles I found:

Checkerboard Brick, Kun version - Kabaya Leaf Japan

A six-piece hollow sphere - two examples.

Each keychain puzzle typically contains six pieces. Here is a photo of a bunch of pieces mixed together. Can you figure out which pieces go with which puzzle?

Adams' Locked Blocks

Adams' Block Puzzle Senior aka Adams' Panel Puzzle - their implementation of the 12 piece Altekruse design.
Here are some disassembly steps:

Six piece burr - Druopta Czech.
This burr uses pieces { 120, 160, 256, 512, 880, 960 } and is an exmple of a design by Philippe Dubois / Gaby Games.
I also have a black example I picked up in Prague during IPP28.

KL # 1 2 3 4 5 6
ID # 188 1024 975 824 1024 1

The fit on mine was very tight. You have to find the key piece 1, KL#6, and carefully slide it out.

Keychain Animals and Riders

This interlocking keychain puzzle is Spunky the Dog - four examples.
A U.S. patent was granted to Irving Hartley Steinhardt in 1953 (2651522) - though the patent was filed in 1947.
In the Feb. 28 1948 issue of Billboard magazine, Kim & Cioffi of Philadelphia were selling a gross of Spunky the Pup Keychains for $13.50. The same outfit is selling a "Keychain Puzzle Pup" in the Apr. 10 1948 issue. The Border Novelty Co. is selling a "Dog Puzzle Spunky Key Chain" for $1.25 in the Oct. 2 1948 issue.
According to Jerry Slocum, Spunky was Steinhardt's pet dog.
Note that the two examples on the left have asymmetric ear widths, while the example on the right and the additional example have symmetric ears.

The six letters in S-P-U-N-K-Y are embossed, one in each of the six pieces - see below.

I found an unusual version of the Spunky Dog - marked Made in Hong Kong in a circle on its head, and "WY No. 50" on its left rear flank. In size it is comparable to a normal Spunky (maybe a tad larger) but definitely less accurately made.

This follow-up to Spunky was called Plasty the Puzzle Pup - see original instruction sheet.

NOTE the shape of the ears, and the tail piece - these instructions match this type of dog.
It is also known as the Scotty or Scottie Dog. Five examples shown.

I found the letters V-P-A-T-O-I embossed inside three pieces of a version of this dog (the other three pieces show no letters) -
I have no idea what they mean - see below:

The large dog puzzle was also offered by Peter Pan in England - here is a Peter Pan Dog on its original card. The pieces are glossier than the previous version, and in six different colors.
At IPP37 I found this unusual version of a dog keychain puzzle, from Druopta.
Note the "uni-ear" and the wide nose.

Keychain Dog - DDR - obtained in a lot from Germany
Here is a keychain puzzle dog made in the DDR -
Note the shapes of the insides of the pieces - they are blockily hollowed out and contain no lettering.

There are several versions of this type of dog with subtle differences in appearance - here are some examples...

Keychain dog examples

In general, I have found that the keychain dog puzzles of this outward appearance fall
into two classes based on the internal shapes of their pieces
and whether they contain lettering - this blocky hollowed type, versus the type where
the hollowed areas are more rounded and contain lettering.
Examples shown below.

Blocky, no lettering:
Keychain dog - blocky internals Keychain dog - blocky internals Keychain dog - blocky internals

Rounded, with lettering:
Keychain dog - letter internals Keychain dog - letter internals Keychain dog - letter internals Keychain dog - letter internals

Of course, the Druopta Czech dog isn't hollowed out...
Keychain Druopta dog

Puzzle Pup Junior keychain puzzle - four examples
Plas-Trix 1949

This version of the Scottie Dog is smaller and has a head like Spunky's and a tail like Pup Jr's. Two examples, but I sold the orange-headed one.

The card shown above identifies this as Plasty the Puzzle Pup, by Toy-Trix.
The instructions on this card show the distinctive tail piece and more squared-off ears of this dog type,
but the larger dog shown above has also been called Plasty.
So, evidently, the name Plasty has been applied to more than one dog type.

The Pal Plastics Scottie Dog card below also shows the pieces of this dog type - note the tail in particular.
However, this card was accompanied by the larger version of the Scottie dog.
Go figure!


Here is a comparison of Spunky and the large and small Scotties.
The large Scottie is on the left, Spunky is in the middle, and the small Scottie is on the right. Each has six pieces.

A small dog issued by Roddy of the UK - similar to the small Scottie Dog above. Three examples including a second but damaged pink/blue one with box.

Here is a five dog comparison:

This Czech version of the Scotty Dog has an "inverted" two-piece head.
The two pieces of the head fit together and into the body only one way.
In the Compendium 2nd Ed. as "Dog 10" #26 on page 5.
I found two examples but sold the green one.
I later found this red version which came to me from Russia:

Keychain Russian Dog - two examples

A Dachshund dog interlocking keychain puzzle (soft plastic) - Kabaya Leaf Japan
Four examples but I sold the white-headed and green-headed ones.

Keychain Mack Bulldog
Minimally interlocking (only two pieces) and minimally a puzzle - but nicely sculpted.

Waldi the dachshund, the first official Olympic mascot.
Created for the 1972 winter games in Munich.
Instructions shown but my example is different -
it has a plastic spine and press-fit tail and ears.
Unfortunately someone glued the head, chest, and first segment together.
Since my first was slightly damaged, I found a couple more.

Spunky Dog - large modern version
A modern copy of Steinhardt's 1953 design (patent 2651522) - issued with different heads, including dog, llama (giraffe?), and elephant. These are larger than the vintage Spunky dog of the patent, and the pieces are hollowed out.
Who let the dogs out??

Compare this to the large modern Spunky Dog above -
here, the ears are swept back. Also, there is no protruding nose.
Is this supposed to be something other than a dog? Maybe a Goat?

I ran across a photo online taken at an exhibition of the puzzle collection of Josef Horda at the Vida Science Center in Brno in the Czech Republic. One display case contained keychain puzzles, and in particular a dog that seemed to have a combination of the ears-forward and ears-backward head pieces. I captured the photos and show excerpts below.

Here are the interiors of examples from my collection of the head pieces of both dog types - ears-forward on top and ears-backward below.

Note that the ears-forward head pieces have a nose and a tab on one half, that sits in a corresponding slot on the other head half. The ears-backward head pieces have no nose, but have a peg on one half that fits into a socket in the other half. (I have three examples each of the ears-forward and the ears-backward dogs, and their configurations are as shown - I do not know of any instance where the slot and nose, or peg and socket sides are reversed.) Neither pair of mixed pieces fits together perfectly, but the slot half will fit with the socket half - resulting in a head with the backwards ear on the left of the face and the forwards ear on the right. I built this dog, shown below. Note that the other pair of head pieces (nose half and peg half) do not fit together - but in the Horda photo, that is the ears combination shown - forward on left and backwards on right!

I am not sure whether the Horda version is yet a third type, or is a Frankenstein whose poor fit is obscured in the available photo. Please let me know if you have any information about this - photos of the insides of the mixed head pieces would be even better!

Two examples of either a Llama or a Giraffe with a fairly short neck

The "Dog Body" style (large) Elephant - two examples

Jumbo the Elephant - two examples
The head is a single piece - note the tab at the top of the back of the neck.

In the Nov. 6 1948 issue of Billboard magazine, the Harris Novelty Company of Philadelphia was selling a gross of each of "Key Chain Puzzles, Elephant" and "Key Chain Puzzles, Donkey" for $13.50 each.

Compare Jumbo shown previously with the similar-looking examples below - each has six pieces. Simplified (Pussy) example in upper left. Soft plastic "split head" example in upper right. Vintage "simplified" example in lower left. Jumbo in lower right.
UL: note hollow head w/ no tab, chain eyelet, lack of pin on right-rear leg (RRL) piece.
UR: note split head, end point sockets for chain, pin on RRL piece.
LL: note hollow head w/ no tab, end point sockets for chain, pin on RRL piece.
LR: note solid head w/ tab, chain channel, pin on RRL piece.

"Simplified" Jumbo the Elephant - 4 examples
The two blue and yellow examples are from the German company Pussy.
Note the absence of the tab at the top of the back of the neck -
also there is no pin on the right rear leg.
The white-headed example is from China - note its instructions are identical to the Pussy German version.

Note the hollowed out legs

"Split Head" Elephant - soft plastic
Pieces are similar to but different from Jumbo.

Keychain Bell Elephant
This nice version by Bell, with its original card, has examples of Bell's characteristic "flesh tone" (caucasian) and light green colored pieces.

Four examples of the "Mechanical Servants" style Elephant
Pair of MS versions on the left, HK copy on the right. Both types made in HK but the MS versions are higher quality. Note the difference in the tail, and the neck insert length.
MS instructions on the left, HK on right. Note that HK instructions do not reflect accurate tail.

Elephant - soft plastic - Kabaya Leaf Japan
Steinhardt architecture variant.
I found two but sold one, then I found another pair.

The card I found calls this "Jumbo" from Lional

Three examples of a German Elephant keychain.
I sold the green one with the red belt.

Hippo (small) - two examples - Kabaya Leaf Japan
Steinhardt architecture variant.

Rhino - Kabaya Leaf Japan

Pig keychain puzzle, with round tail.
The first pink and black version is higher quality (from Pussycat of Germany?)
This design is similar to the MS Elephant construction.
In the Compendium 2nd Ed. "Pig 1" No. 66 on p11.

This version of the pig has a straight, flat tail as opposed to the round-tail version, but its architecture is the same.

This version of the pig has rounded ears.
In the Compendium 2nd Ed. "Pig 2" No. 67 on p12.
Thanks, William!

This version of the pig has rectangular ears drooping down.
In the Compendium 2nd Ed. "Pig 3" No. 68 on p12.
The seller was in Germany.

This version of the Pig comes from the Czech Republic.
In the Compendium 2nd Ed. "Pig 4" No. 69 on p12.
My copy has some surface damage.

This version of the Pig comes from the DDR - three examples

Another eye test - Keychain Puzzle Pieces Jumble #2 - can you tell which pieces comprise which puzzle?

Desert Patrol / Camel Rider keychain puzzle - 3 examples
Listed in the Compendium 2nd Ed. as #89/90 on p15.

Mule Train or "Burro and Rider" or "Mule Rider"
A version was issued by Lional 1954
Listed in the Compendium 2nd Ed. as #92/93 on p16.
17 examples
(The Sombrero isn't a puzzle but is sometimes seen accompanying the Mule Rider.)

Interestingly, there is a design patent on this puzzle - D161829 Goodman - issued 1951, filed 1949.

"Don" Key (Donkey) keychain puzzle - three examples.
See the instructions - this one has only five pieces but requires various rotations.
Plas-Trix 1949

Lional Indian Raid set
Includes two Indians on horseback, each holding a tomahawk in the right hand
and two cowboys on horseback, each holding a pistol in the right hand.
Listed in the Compendium 2nd Ed. as #19 in the Appendix - Multiples-2 section.

Cowboy with pistol in right hand -
one additional (loose) example
Listed in the Compendium 2nd Ed. as #82 on p14.

Cowboy with pistol in left hand - 2 examples
Not listed in the Compendium 2nd Ed.
Maybe these are riflemen with the rifle butt broken off, but I found examples from different sources and they don't seem damaged.

Cowboy with rifle in left hand - 3 examples
Listed in the Compendium 2nd Ed. as #83 on p14.
NOTE that this rifleman and the cowboy with pistol in LEFT hand share a style of horse that is distinct from the horse shared by the Lional cowboy, indian, and scout/ranger. Instead this horse appears similar to that of the Kentucky Derby puzzle made by Pal Plastics.

Indian with tomahawk in right hand -
four examples including an all-black example.

NOTE the Compendium 2nd Ed. lists only an Indian on horseback with a tomahwak in the LEFT hand, #84 on p14.
It says that version is soft plastic and from Hong Kong.
This version is the Lional hard plastic type included in the Indian Raid set, so I am surprised it isn't listed.

Keychain Mini Indian on Horseback
Listed in the Compendium 2nd Ed. as #91 on p16.

Scout or Ranger (aka Mounted Police) (no firearm) - 2 examples
Listed in the Compendium 2nd Ed. as #87/88 on p15.
All of the Horse and Rider puzzles assemble in the same basic way, with a rotating tail piece as the key.

Listed in the Compendium 2nd Ed. as #86 on p15.

Bucking Bronco or Ride 'Em Cowboy keychain puzzle - four intact examples
Listed in the Compendium 2nd Ed. as #80/81 on p14.
This puzzle is my least favorite - it holds together poorly and the key on the head is very fragile.

A Cowboy keychain puzzle produced in England 1995 - three examples
Listed in the Compendium 2nd Ed. as #94/95 on p16.

Lucky Duck keychain puzzles - six examples
a.k.a. "Lucky Ducky"
Note on instructions in step D - "Find Egg Inside" - I found a copy of the Lucky Ducky with an egg still inside!
PT - Pal Toy or Plas-Trix

Puzzler Duck in Cannon Package

Duck in Top Hat - seven examples
I have instructions from the German company Pussycat.

Keychain interlocking puzzle Duck with Sailor's or Seaman's cap - four examples

Note that the Lucky Ducky is wider than this version:

Its belt and loop pieces are correspondingly larger.

Bell Goose interlocking keychain puzzle - three examples

At the Antarctic!
Keychain interlocking puzzle Penguin
A very small, soft plastic puzzle from Kabaya-Leaf of Japan. Four examples.

I found this keychain Penguin similar to the Kabaya Leaf Penguin, but having a loop on the head, a sharp beak rather than the KL's rounded beak, and only four pieces. It arrived in a plastic gumball machine capsule.
A second instance has an opposite color scheme.

Keychain interlocking puzzle Rabbit
A very small, soft plastic puzzle from Kabaya-Leaf of Japan.

Keychain interlocking puzzle Owl
A very small, soft plastic puzzle from Kabaya-Leaf of Japan.

Keychain interlocking puzzle Owl - alternative pieces
A very small, soft plastic puzzle from Kabaya-Leaf of Japan.
This version has a single-piece head.

This type of Owl keychain puzzle has been issued in both soft and hard plastic.
I have instructions from the German company Pussycat, which issued the green and yellow hard plastic version shown below with the marking "DBGM."

Here is another hard plastic example. Note that it differs from the Pussycat version by having a shoulder eyelet, and lacking a tab on the neck piece.

Here is an assortment having different keychain attachments.
The third from left is soft plastic - one piece is marked "Hong Kong" and has a 'W' on the inside.

Keychain Rooster - two examples

Monkey keychain puzzle (three examples shown but I sold the one with the green belt)
The body can be installed with the "belt" either in front or back and
the arms or legs can be swapped side-to-side. I am not sure of the intended configuration.

Keychain Fish from Pussy of Germany
This one has an interesting springy internal piece that when squeezed opens the mouth.
I found another instance of the Fish by Pussy - this one in a package for ZeoZon, with instructions.

The ZeoZon Fish has the same architecture, including the spring, as the Pussy Fish - but its spring is blocked by a piece of plastic. The interior of the side pieces are slightly different, too. But both have DBGM on the jaw piece.
Here is a comparison of the Hong Kong fish, the Pussy Fish, and the ZeoZon fish.

The eyes of the Hong Kong fish bulge outwards, while the eyes of the Pussy fish dimple inwards.

This version of the Fish is from Hong Kong and is so stamped on the tail. It has a simplified body and omits the spring and opening mouth. Fit is poor.

Fish, soft plastic - Kabaya Leaf of Japan

Keychain Piece Jumble #5

Puzzle Puss - three examples. Also showing two slightly different cards (can you spot the difference?) and a tear-off paper instruction sheet complete with tear!
Also issued by Bell and called the "Lucky Cat."

Lucky Cat - Bell UK
Comparison of faces of Lucky Cat (center) and Puzzle Puss (left and right):

Frankly, I see no differences.
The Lucky Cat fits together much more tightly than any Puzzle Puss I've run across, though. Ahem.

Here is a Bulldog using the Lucky Cat architecture.
This one is absent from the Compendium 2nd Ed. and seems rare.
Shown for reference (I do not have this):

Thanks to Karen for the photos!

Keychain Horse puzzle.
A blue version (Dutch, vinyl) - missing the ears (a common issue),
and a hard plastic version from Germany in its package.
Yes, the German version has its ears, but someone glued them in.

Here is a Poodle, obtained from a seller in Poland, which shares the architecture of the Dutch/German Horse puzzle.
The poodle is made from hard plastic.
The head piece slides out first.
This puzzle poodle does not appear in the Compendium 2nd Ed. and seems very rare.

Speaking of rare or unusual puzzles featuring the Dutch Horse body architecture,
here are photos I snagged from the web of another variant, having a dog head, with no mane.
Shown for reference (I do not have this):

It seems to have been assembled with the "belt" piece in an incorrect orientation.

Keychain interlocking puzzle Boar or Hedgehog (Germany) - four examples

Butagaz Bear Keychain puzzle
Very rare! But I did manage to find two.
My first was slightly damaged - the piece in the lower right should
have a tab projecting forward and up to lodge between the legs.
Still very happy to have found it.

Found an intact example and traded away the other.

A very rare Giraffe keychain puzzle, produced in the 1950s-60s by Roddy in Southport, England.

Keychain puzzle Giraffe - Kabaya Leaf Japan

Keychain Dragon (large version) - three examples
All soft plastic.

The Dragon also appears in a small version.
It has the same pieces as the large and is also soft plastic.
Here is an example in its package, with a size comparison to the large Dragon also in its package.
Also shown is a loose mini Dragon and its pieces.

Alligator (soft plastic) - Japan - Kabaya Leaf Inc.

I found an instance of this Kabaya-Leaf puzzle in its package, complete with the instruction sheet shown here.
Although this puzzle resembles a Curling Iron, the instruction sheet says four different animals can be constructed - with all pieces used to make a Snake.
Soft plastic. Kabaya-Leaf Japan
Six examples shown.

  • つばめ means Swallow
  • すずめ means Sparrow
  • はくちょう means Swan
  • ヘび means Snake

I found three but kept only one.

Brontosaur - Kabaya Leaf Japan
I obtained two but sold the white-headed example.

Keychain People, Robots, and Other Figures

William Waite was kind enough to provide some info on what I thought was called the "Contortionist" keychain puzzle. It turns out this model is actually known as the Wha Hoppen or Wrestler puzzle. The hapless wrestler has been tied into a pretzel by his opponent. I finally obtained an instance including the original card. This was marketed by the Harrison Co. of Long Island City NY in 1951.

Here is the Bell version, called the Wrestler, on an original card.

Five additional examples of the Wrestler.

Bibendum (Michelin Man) puzzles. This is the small version.
As a kid, I had a Bibendum keychain puzzle I got at a car show at the NY Coliseum.
It disappeared long ago, but after searching for some time, I finally found another one.
This puzzle is the last of four "Lost Puzzles of My Childhood" (Drive Ya Nuts, Phony Baloney, Screw Loose, and Bibendum)
that originally motivated me to start following auctions!

Bibendum - the medium sized version.

Bibendum - the large sized version.
Architecture is similar to a kumiki puzzle.

I also found two in their packages:

Bibendum Trio

After finding the above Bibendum versions, I learned from Peter Hajek of the existence of a variant of the largest Bibendum - whose key piece is wider than that of the version shown above, with a correspondingly smaller left hand piece. At IPP37 in Paris I discovered a copy of this wide-key variant, shown below with its accompanying card and in comparison with the narrow-key version.

Narrow-key variant on the left in all comparison pictures. Note that there are other minor internal differences, including internal grooves on the shoulder and hip pieces, and circular tabs on the sliding pieces of the wide-key version, and different tabs on the right hand piece.

Blue version of the large, wide-key Bibendum

Esso Oil Drop Man interlocking keychain puzzle - 2002
Hard plastic, 8 pieces. The chest is a front and back fixed together.
(Seems permanent to me and I didn't try to pry it apart -
the legs and arms have flanges and slide into it in grooves.)
Very happy to have found this extremely rare keychain puzzle!
In pristine condition, to boot!

Since this one is so rare, I have taken photos of the [dis]assembly steps.

宇宙人ピピ パズル (Alien Phi Phi or PiPi Puzzle) -【メーカー】ジュニア Manufacturer: Junior (Japan) 1960s
Listed in the Compendium 2nd Ed. as "Elf 1" No. 102 on page 17.
My green example is missing its face disk and the nose pin.
From a Japanese description:
"It is a puzzle figure named Phi Phi from a children's drama series "Alien Spirit"
written by Sakyo Komatsu and directed by Kazumasa Hirai with music by Isao Tomita
that began broadcasting on NHK in 1965."
The show was a pioneering blend of live action and animation.
See the Wikipedia Japan entry for Alien Spirit.
Watch a sample episode at the NHK archive.
This puzzle was produced in the 1960s by the manufacturer "Junior"
in various colors including yellow, green, red, and blue - the TV character was yellow.

I found a second example. This one has a face piece but was missing its nose, so I made one out of spare green plastic.

This Japanese cartoon figure is called "Naruheso-kun" (なるへそくん or なるへそ君くん ) which translates as "Navel-Boy." - Japan
Note the ball bearing that came inside the head to make it rattle.
According to the blog Before Mario, "the character Naruheso-kun was created by Aoui Yamane. Naruheso-kun is a cartoon figure whose main claim to fame is a violently popping navel. The Japanese word for umbilicus is actually 'heso' so his name translates to Navel-Boy."
NOTE that the card that accompanied this puzzle character says ヤダモン which is "Yadamon" so I first thought that was this character's name, but images of the Yadamon character do not feature the navel nor do they much resemble this character - images of Navel-Boy are a much better match.

This Japanese cartoon figure is Q-Taro - Japan

This version of the Q-Taro keychain puzzle came with its original box.
This puzzle borrows the traditional Robot puzzle architecture.

I don't know what cartoon figure this is, but it came from Japan
A bit racoon-like.
It has only five pieces but it seems complete.
The yellow example may be missing a ball-like tail.
I have seen this referred to as a "Tanuki" (たぬき) - a Japanese Racoon-Dog.

This is a cartoon character Perman (see the Wikipedia entry about Perman) - Japan

Keychain Topo Gigio - Japan

Ninja - Japan (Maruka)
忍者 - means ninja
In the Compendium as Ninja #118 on p20.

Elf - Japan
In the Compendium 2nd Ed. as "Elf 2" #103 on page 18.
孫悟空 means "Sun Wukong" or the Monkey King
組立説明図 means "assembly drawing"

Crazy Kid - Japan
In the Compendium 2nd Ed. as "Kid with Hat" #106 on page 18
However, note that the example in the Compendium differs from my example in several respects,
including the cap, head, and eye structure, as well as the arms, torso, and legs,
and finally the card -
so evidently there exist at least two different versions of this puzzle character.
I did not disassemble the lower section including the legs - the pieces of this puzzle are fairly fragile.
怪物くん means "Monster-kun" which was a Japanese television show featuring a boy like this character.

I obtained an example of the Monster-Kun Kid puzzle shown in the Compendium 2nd Ed as "Kid with Hat" #106 on page 18.

The puzzle includes a small ball bearing rattling around inside the head.
Comparison with other version of the Monster-Kun kid.

Japanese Diver keychain puzzle.
Three examples - one in its original package.
Slocum and Waite identify this Japanese interlocking keychain puzzle as a Diver, but it reminds me of Gigantor.

Shmoo - two examples, one with original card
Toy-Trix 1949
Also shown - excerpt from Billboard magazine of May 1949 offering "Shmoo Puzzle Keychains with fortune" at a dozen for $1.50 or a gross for $16.20.

As indicated on its card, the Shmoo originally contained a fortune - on a small slip of flimsy paper and nestled in the cavity in the white piece shown at bottom center in my photo of the puzzle's pieces. I found an intact example in one Shmoo!

Aside from the head and tail pieces, the Shmoo puzzle is equivalent in architecture to the Lucky Duck keychain puzzle issued by Pal Plastics, which also appeared as the Lucky Ducky that itself contained a fortune - one instruction sheet promised 'Find your fortune inside "Lucky Ducky."' (See step D in instructions shown below - "Find Egg Inside.")

Here are some interesting facts about the Shmoo, from Denis Kitchen's website, the Wikipedia article on Capp, and the Wikipedia article on the Shmoo:
By the postwar 1940's Al Capp's comic strip "Li'l Abner" - created in 1934 - had millions of fans and had made him millions of dollars. In August 1948 Capp (b. Alfred Gerald Caplin 1909 in Connecticut, d. 1979) introduced a new character called the Shmoo, which became an unprecedented merchandising phenomenon, spawning dozens of Shmoo-themed products and lasting through 1952 - and generating over $25,000,000 in sales in one year (in dollars of the time - more than $200 million today). Shmoos packed with candy were dropped by the U.S. during the Berlin Airlift. A Shmoo Savings Bond was issued by the U.S. Treasury Department in 1949 - Al Capp appeared with President Truman at the unveiling ceremony. Shmoos appeared alongside Capp on the cover of Time magazine in 1950. For a not-so-flattering account of Capp and his strip, see an article The Brand Called Shmoo by Daniel Raeburn at the Baffler website.

"The Shmoo is shaped like a plump bowling pin with legs, but no arms." Oddly, the card shows a Shmoo with arms, but the iconic character has none. More Shmoo trivia - Shmoos are white - there are evil Shmoos called Nogoodniks and they're green colored.

Below are examples of "Robot 1" #135 on page 23 of the Compendium 2nd Ed.

Robot 1 is distinguished by having: no chain/cord mounting point, a two-piece head, and a right-shoulder piece that internally has a hook around the neck, such that the head/neck must come out first. Also, the thick part of the neck on the left is subtly engineered to have a small protrusion that snaps it into the body when inserted.

This black and white one came from Russia.
Note the different, more linear, neck, and the different eyes.
Otherwise the architecture is the same, and this robot also has no chain/cord mounting point.

This variant of Robot 1 has a loop on its left shoulder. Its head is still two piece and the right shoulder hook arrangement and head-out-first is the same.
Two examples - the green translucent one is from Pussycat of Germany, the purple-headed one is from China.

Two instruction sheets shown - the 102217 sheet is from Pussycat of Germany, and the Made in China sheet accompanied the purple-headed robot. The Chinese sheet is essentially a copy of the Pussy sheet.

There are several more examples below from different sources of the Robot 1 with a left shoulder loop.

Mechanical Servants Robot
Standard, plain two-piece head, head pulls out as first move, loop on left shoulder.

Robot with All-Stars card

Keychain Robot in package - China

Examples of Robot 1 with shoulder loops, from Japan.

Keychain Robot in box - Japan - Tamaki

I found a second example:

This version of the robot has a chain embedded in the left shoulder.
Four examples, two used for advertising (BASF, and Karo-As Cutlery).
One has bejeweled eyes, three have the marking DGBM on the neck tab. I believe the DGBM examples were issued by Pussy of Germany.

These all still use the hook inside the right shoulder, and head-out-first - note the subtle locking protrusion on the yellow bejewelled DGBM neck piece.

Comparison with other similar robots shown.

This Robot has a chain loop on its head.
It is hardly legible, but the back of the head says "HONG KONG."
Note that this one also has the provision for the chain to be embedded in the shoulder - two holes can be seen in the left shoulder.
This one has a major architectural difference - here, the right shoulder must be removed first, only then can the head/neck be extracted. The right shoulder piece has no hook, instead it has an indentation to accommodate a "pin" protruding laterally from the neck. If you try to pull the head out first, you will likely break this pin!

NOTE the 'T' shaped neck piece with pins, and how the right shoulder pieces have no hook but rather a notch underneath to accommodate the neck pin.

"Robot 2" #136 on page 23 is similar to Robot 1 but has a hollow one-piece head, and a shoulder loop. Two examples.

This robot has kind of a TV antenna on its head. Japan.
This is "Robot 3" #137 on page 23 of the Compendium 2nd Ed.
Two examples.
Of note is the difference in this robot's architecture, similar to the HK robot - usually one can first pull out the head, but in this case one must first remove the top right arm piece before the head can come out. You can see the pronounced protrusion on the neck piece which locks it in place under the arm piece.

One body piece has text on it: サロンパス which translates as "Salon pass." Looks like they make bandages. Maybe advertising?

This version of the robot has a sharp nose, pronounced mouth, and a head fin - Japan
This is "Robot 4" #138 on page 23 of the Compendium 2nd Ed.

Keychain Robot with Long Legs - three examples
This is "Robot 5" #139 on page 24 of the Compendium 2nd Ed.

After I bought these, I found a Japanese store card of the Long Leg Robot but it is missing one robot (though I suppose I could simply replace it).

Astronaut with Capsule
In the Compendium 2nd Ed. "Robot 6 - Astronaut" No 140,141 on p24.

NOTE that "Robot 7" #142 on page 24 is what I list as the simple (no claws) Berlin Bear with pentagonal crown.

Keychain Russian Robot - from a seller in the Ukraine
Architecture similar to the Berlin Bear
Appears in the Compendium 2nd Ed. as "Robot 8" #143 on page 24, where the country of origin is listed as East Germany (DDR).

I obtained one from Russia, in its bag with an instruction sheet:

Keychain Czech Robot
This faceless robot with large disc ears is not listed in the Compendium 2nd Ed.
Architecture similar to the Berlin Bear.
This red example came to me from Russia:

A small robot - Kabaya Leaf Japan
This is "Robot 9" #144 on page 24 of the Compendium 2nd Ed.

Klaatu barada nikto!

Mini version of the Keychain Robot
I found three examples but none disassemble.

This tiny robot from Japan is not a keychain puzzle - but this particular character appears frequently as a container.

I obtained this storecard of big robot puzzles from Japan.
The nice, colorful graphics on the storecard - a rocketship and a blaster-wielding space cadet - are hidden behind the puzzles.

This robot does have six pieces and a keychain loop, but it is fairly large
and has a simpler architecture than the common robot puzzle - it is held together by two rings.
This version is not in the Compendium 2nd Ed.
Below is a comparison with other robots.

A Martian - based on the Robot design.
This is "Space Man 2" #127 on page 22 of the Compendium 2nd Ed.

Three Ladybugs (two of orange/pink, and red/black German Pussycat version)

Ladybug (soft plastic) - Kabaya Leaf Japan

Dragonfly keychain puzzle - soft plastic - six examples

This example is different and may have been issued by Kabaya Leaf Japan (I received it from Japan).
Note the lack of an eyelet and the smaller dimensions.
This is 32mm long with a 9mm tail, versus the normal 37mm with a 12mm tail.

Keychain Butterfly - two examples - Kabaya Leaf Japan

Keychain Grasshopper puzzle - Kabaya Leaf Japan

Keychain Cicadas - three examples

A keychain Beetle (with no horns) - two examples.

Rhinocerous Beetle - soft plastic - three examples (two in packages)

Keychain Artifacts
Score A Touchdown Football keychain puzzle - three examples
Plas-Trix 1949

In the Nov. 5 1949 issue of Billboard, Joker Novelties of New York was offering a "Football Puzzle Key Chain" at $8.40 for a gross.

This may resemble a Steinhardt configuration, but it is a distinct design and comes apart/assembles differently. I show pictures of the steps.

This one has been variously called the All-American / Cum-A-Part / Five Segment / Try A Pencil Football keychain puzzle - three examples

The letters T-R-Y-A-P-E-N-C-I-L are embossed in the pieces, two letters to a piece. One is supposed to poke a pencil in the tip to pry the pieces apart.

In 1955, Irving Steinhardt received patent 2712447 for this type of football keychain puzzle, called the "sector puzzle construction."
Note that the actual puzzle differs a bit from the patent - the loop is on one of the five segments rather than on a separate sixth segment of its own.


Here is a Football puzzle from Kabaya of Japan, in soft plastic. It looks like it would be a copy of the sector puzzle construction -
but its internals are completely different and it has six pieces.
Two examples - red and yellow

Here is another Football puzzle I received from Japan, in soft plastic. It has only four pieces.

This four piece Beachball puzzle also came from Japan.

I found three examples but kept only one.

Here is a very simple 2-piece version of the ball, from Japan.


Keychain interlocking puzzle Volleyball (?) - Kabaya Japan. Soft plastic.

Tennis Ball (?) (soft plastic) - Kabaya Leaf Japan
Two examples - yellow and blue
To me this looks like a tennis ball, but in the Compendium 2nd Ed.
it is listed as Basketball 2, #219 on p37

Keychain Soccer Ball - two examples - black spots and white spots.
I have instructions from the German company Pussycat.

Two colorful examples from Israel:

Soccer Ball - Kabaya Leaf Japan
A very different architecture than the "traditional" soccerball.
I'd never before seen pieces designed to fit by flexing.

けん玉 Kendama puzzle - Japan
Hard plastic.
13 pieces for the body, 3 for the ball, plus one string.
Kendama, or Sword and Ball (a variant of Cup and Ball), is a popular dexterity toy in Japan.
See the Wikipedia Japan page on Kendama.
Listed in the Compendium 2nd Ed. as Cup & Ball 1, No. 233 on page 39.
The pointy-tipped rod (red here) slides out first, releasing the locking piece in the base (yellow here).
One of the base halves (the black one here) has a tab near its narrow end that locks it into the crosspiece -
so the base halves must be removed/inserted into the crosspiece hole one half at a time.

Kendama Puzzle - Japan
a boxed version, still on sprues

Jingle Bell - Japan
A second example did not contain an actual bell:

Keychain Legal Coffee Grinder (French) - two examples
The pieces are basically the Steinhardt cube.

Kumiki Barrel - three examples.

Keychain Barrel Puzzle in package - China

A hard plastic barrel was issued by Kawada Japan

Lucky Mallet puzzle - Japan
Same architecture as the Kumiki-style Barrel

Keychain Barrel - Kabaya Leaf Japan
This Barrel has an architecture distinct from the usual barrel.

A keychain puzzle Bell was issued by the German company Pussy. Their version is made from a high-quality plastic and is well molded. The letters DBGM are molded into the bottom piece. The chain is embedded into the stem piece. Two copies are shown. I also obtained a copy from Israel - it is the same design but the inscription is missing and the plastic is more brittle. Its chain runs through a loop on the top.

Here is the copy from Israel:

Here is another copy of the Bell, from Kabaya Leaf Japan - note the difference in the stem:

Two examples, one came with a box. Hard plastic.

The bells issued by Pussycat and by KL are of two different sizes - KL's being smaller and having one less segment - here are several for comparison:

Dice keychain puzzles - three examples, with three different styles of chain attachments
I've had the white one since I was a kid.
I have instructions from the German company Pussycat.

Dice puzzle - soft plastic - Kabaya Leaf Japan
A different architecture than the Pussycat version.
The KL version relies on a flexible tab, and a friction-fit peg in hole.

I found a blue example, too:

This is the large Kun version of the puzzle Die - Kabaya Leaf Japan

Lufthansa Supercargo Crate advertising keychain puzzle.
This has quite a few more pieces than the typical keychain puzzle!

Keychain Cheese Wheel - Wine and Cheese!
Four examples, one without stickers

Keychain interlocking puzzle Circuit Breaker (France) - four examples

Keychain interlocking puzzle Mini-Stotz Circuit Breaker (Germany - BBC)
Same basic architecture as the Robot.
Also has a small red "jewel" on the bottom of the green piece -
I imagine it is meant to represent an indicator.
Last image is a real mini-stotz.

Keychain Trophy - Japan
Two examples - gold in package, and loose silver. Also available in multicolored.
A nice assembly, with robust plastic. I really like this one!

I found the colorful version, too.

Spray Bottle (France) - three examples

Keychain Terramycine Bottle (yellow) - France

Kodacolor - France

Sarazin - France
Same architecture as the Kodak Box

BP Longlife Can - two examples

Lithol Can

Avioline Can - same architecture as BP Longlife can

Keychain interlocking puzzle Oil Can BP T.O.U. - two examples
The Oil Cans and the Kodak Box puzzles employ similar mechanisms.

Antargaz Can puzzle - France
A Steinhardt architecture puzzle.
The keychain attachment must be removed for the key piece to slide down and out.
The non-puzzle form of this Antargaz Can keychain seems very common.

Keychain Lucky Charm - two examples

Two examples of a Lantern keychain puzzle
Note the difference in the corners on the base. The orange version, with rounded corners, was made by Pussy of Germany and is of higher quality.

This version of the Lantern is from Hong Kong

Legal Coffee Bean - four examples

The Legal Coffee Bean and Steinhardt Cube puzzles employ similar mechanisms.

Heart and Arrow keychain puzzle from "Mechanical Servants"
Also two examples of same heart but without the arrow
Has a rotational move - see step (E).

Heart on All-Stars card

I finally acquired an example of the very rare Peter Pan UK version of this puzzle with its heart-shaped card.

Heart and Arrow keychain puzzle - Peter Pan UK
The heart-shaped card is smaller than I expected it to be.

Heart interlocking keychain puzzle - three examples.
The pink one is by Pussy. The colorful one is from HK.
The architecture of this type of heart is similar to the Bell Goose.
I have instructions from the German company Pussycat.

Compare to the bottle below.

Another Bowling Pin - similar construction but this one is fatter. Three examples.

Bowling Pin Keychain Puzzle in package - China

This bowling ball and pin came in a set of puzzles by Kawada, from Japan. The "Fat Pin" style. Ball is Steinhardt config. Second bowling ball also shown.

Bowling Pin and Ball set - Japan
ボーリング means bowling
Both the pin and ball in this set have novel architectures - the pin is formed around a central spine, and the ball is not quite a Steinhardt configuration - it has only five pieces.

Another set from Japan, but with a "thin" style pin.

Comparison of Bowling Pin puzzles

Keychain Bottle - two examples

An extra-large keychain bottle puzzle - two examples

Another example of the large bottle - this one labeled as Beer.

Keychain Movie Camera puzzle - the orange one is from Pussycat (Germany).
Four examples. Two marked "Bauer."

Drill (Peugeot France) - three examples
The pieces of this puzzle can sometimes get wedged very tightly together. Take a look at the instructions - don't break yours trying to pry it apart! The bit/chuck comes out first, then the handle, then the top front cowl slides forward.

Good Luck Horseshoe or Lucky Horseshoe keychain puzzles - four examples

The Horseshoe was available with three different inserts: horsehead, clover, and Davy Crockett (in order from most to least common).

Lucky Horseshoe keychain puzzle on alternative card - Pal Plastics

The Good Luck Horseshoe with Horse Head also was issued in a small version.
The height (including the loop) and width (at the widest point of the horseshoe) of the large version are 1 7/8" (48mm) x 1 5/8" (42mm).

This one does not spin well at all, though I did manage to get a photo of it spinning.

Keychain puzzle Windmill (Czech) - two examples
The Windmill shares architecture with the Lantern, but here
the Lantern is upside down and its base is inverted.
The roof is friction fit.

This Old-style Telephone Interlocking Keychain Puzzle was designed by John Flower in 1952
and issued by the UK company Bell.
It has six pieces and assembly requires several pieces to be moved back and forth in sequence,
which is not typical for keychain puzzle mechanisms.
I like this one a lot!
This was designed by John Flower in 1952. 92,000 produced.
I show instructions for reference - but I do not have the card for this puzzle.

This hard plastic Telephone puzzle is from Japan. Issued by Ito.
It is #210 on p35 of the Compendium 2nd Ed.
The instructions come from the "Head Sports" set card.

This keychain Telephone puzzle is from Kabaya Leaf Japan,
part of their "Big League Chewing Gum" bonus series.

Samurai Helmet () - Japan
One in a series (シリーズ) of at least four - this particular helmet represents Minamoto no Yoshiie (源 義家) - long antler pair

Fellow keychain puzzle collector William Waite has a complete set of four and has supplied pictures of the others.

The others include:
Kusunoki Masashige (楠 正成) - trident

A Pagoda in soft plastic - Japan - Kabaya Leaf Inc.

Pagoda (hard plastic) - Japan
This is probably intended to be a model of picturesque Nagoya Castle.
Two examples shown, one in its bag with instructions.
I have another incomplete copy and scanned its instructions, shown.

Tokyo Tower (hard plastic) - Japan
東京タワー means "Tokyo Tower"
The Compendium 2nd Ed. lists this as #277 on page 47 "Eiffel Tower 1" -
but though the Eiffel may be more iconic,
the instructions that accompanied my copy clearly call this the Tokyo Tower.
The Tokyo Tower puzzle came with an instance of the Nagoya Castle puzzle,
molded in virtually the same plastic and colors -
I surmise these puzzles were produced by the same manufacturer.
Note, however, the differences between the previous Nagoya Castle instructions and these - there probably were multiple issuers of the Castle puzzle.

means "Castle"

Pyramid (soft plastic) - Japan - Kabaya Leaf Inc.

Puzzle Tower (Eiffel Tower?) - Kabaya Leaf Japan (soft plastic) - two examples

Blackpool Tower, original card - Merit UK
Very rare. Also issued with pieces in colors - see Compendium p. 46 #275,276.

Details below...

American Flag - soft plastic - Kabaya

Union Jack Flag - soft plastic - Kabaya

French and Finnish Flags - soft plastic - Kabaya Leaf Japan

Television - Japan
Hard plastic.
With instruction card.

I found several additional examples, each having a different image.

The keychain community had previously thought this puzzle from Kabaya Leaf of Japan was representative of the Kokugikan Sumo Stadium, however now this is believed to be one of a series of three "Gemstone" puzzles illustrating different gem cuts. See the next two KL puzzles...

When I first found this, I didn't know what it was meant to represent, so I called it a "Squashed Halfdome." I now believe this is one of a series of three Gemstone puzzles illustrating different gem cuts.
soft plastic - Kabaya Leaf Japan
I found three but sold one.

With the discovery of this puzzle issued by Kabaya Leaf of Japan, William Waite (who owns this example - I lost the bid) and I now believe that the puzzles previously known as the Kokugikan Stadium and the "Squashed Halfdome" are along with this one three Gemstones illustrating different gem cuts.

Nut and Bolt - Kabaya Leaf Japan

Coin Box - Japan

This Walkie Talkie (aka "Transceiver") puzzle shoots plastic "bullets" and came in a set of spy gadgets including a bullet-shooting lighter and bullet-shooting folding knife. Only the Walkie Talkie is an interlocking puzzle. From Japan.
Shown in the Compendium 2nd Ed. as "Walkie Talkie" #214 on page 36.
The antenna extends and retracts as one rolls the knurled side wheel.

Keychain Guns, Cannons, & Tanks

Raygun or Space Gun puzzle keychain - five examples, one with card.
A version was issued by Pal Plastics Inc. of New York.
Also Plas-Trix 1954

Here is the Bell version of the Space Gun, with original card.

Mini Space Gun 1985
It's got only five pieces compared to six for the full-sized Space Gun - the nose is a single piece rather than two.
The nose holds on only via friction so I imagine it is easily lost.
Two examples.

A Tiny Gun - Kabaya Leaf Japan

Interlocking Derringer - Japan

A Pirate's Pistol - Japan
Thanks, Jaap G!

Keychain Kumiki Pistol - Hong Kong, 1981?

Machine Gun or Tommy Gun keychain puzzle, issued by Lional 1961 - five examples

The Mystery Six Shooter Puzzle or Pistol or Revolver Puzzle
Four examples. I have an original card, and a separate instruction sheet (green) - both shown.
Also shown - comparison with Roy Rogers Straight Shooter.
The Mystery Six Shooter was issued around 1950, I believe, by Champion Plastics -
I found a reference in the July 1950 issue of Billboard.

(Note that the Roy Rogers gun's chamber is in two pieces as part of the barrel and doesn't
revolve, so the gun referred to in the magazine is definitely not that one.)

A version of the Mystery Six Shooter Pistol Puzzle issued by Peter Pan in the UK

The Roy Rogers Straight Shooter Gun Puzzle Keychain - eight examples.
A version was issued by Plas-Trix Co. of Brooklyn New York (in 1951)
I obtained one with an original card.
Examples of this puzzle often suffer from warped handles where the halves have separated at the heel and sometimes at the tip of the barrel.
Also shown - comparison of pieces with Mystery Six Shooter.

Keychain Cowboy Straight Shooter, with card
This puzzle gun has also been offered as the "Roy Rogers Straight Shooter."

This interlocking keychain puzzle revolver came from Israel. Five examples.
As you can see from the photo of its parts, it is distinct from the two other revolver puzzles I have.

A trio of interlocking keychain puzzle cannons, one in its package.
a.k.a. "Action Cannon"

Field Gun - Merit 1954

Artillery Gun or Field Gun - HK copy - two examples

I have four loose variations of the Field Gun -
the one with no markings is a soft plastic Jig-Toy;
one HK version is marked "NOXIS";
another HK version is marked simply Made in Hong Kong;
the Merit version is marked "Made in England."

This Field Gun came from Japan.

This is the "Action Puzzle Toy" Field Gun.

This miniature Field Gun puzzle is part of a set of three miniature puzzles (Field Gun, Jeep, Destroyer) issued in Hong Kong.

Interlocking keychain puzzle Tanks - three examples
PT - Plas-Trix

The same tank - even down to the PT logo on the base -
accompanied this different card issued by Pal Plastics.

An interlocking puzzle Personnel Carrier (Tank) from Japan.
In the Compendium 2nd Ed. as "Personnel Carrier" No. 397 on page 67.
The Compendium says the manufacturer is Ito.
I have a copy that is missing two wheels, but I found an intact store card.

On the top of the instruction card:
コンバトカー means "combat car"
パズルコーナー means "puzzle corner"

To the lower right of the main picture on the store card:
イギリスの means "England of" or "English"
装甲車 means "armored car"
サラテイン means "Saladin"

This is a model of the FV601 Alvis Saladin armored personnel carrier.

The logo in the lower left of the top of the card seems to read:
正ちぺん which transliterates as "Masa Chi Pe N" -
translations include "Regular" and "Right Side" but I am not sure how to properly read the logo.

The compendium identifies this as a Walker Bulldog Tank - Japan
Here is a colorful example I found in its package. It is the "M-41" tank, by ODK.

This is a British Comet Tank - Japan
#405 on p68 of the Compendium 2nd Ed.
The first copy I found is damaged and the barrel is missing.
I found additional damaged examples, with packaging, and was able to construct a fairly intact example.
However, the treads are problematic - they are too tight and had melted onto the wheels and body.

モグラ means "Mole"
タンク means "Tank"

A "Mole Tank" - Junior, Japan

Half-Track - Japan
Listed in the Compendium 2nd Ed. as "Armored Truck" #355 on p60.
I obtained my example as part of a "Head Sports" set from Japan.

Circle the Wagons!

Covered Wagon (or Conestoga Wagon) by Plas-Trix 1954?
Eight pieces - the canopy and wagon are split lengthwise.

Stagecoach keychain puzzle - two examples - Lido
Also a store display card:

Merit Stagecoach Keychain puzzle

This is the very rare Lord Mayor's Coach puzzle by Bell (UK).

As is usually the case concerning this particular puzzle, the "tongue" piece that would normally jut from the undercarriage forwards between the front wheels, is broken off. In the image of the underside, one can see the stub of the tongue piece - it is affixed (glued?) down the centerline of the bottom piece of the cabin - I believe the tongue and the cabin bottom were a single unit (note the seven pieces). The instructions say to move the "centre" piece (indicating the tongue) "left" but I believe this caused confusion resulting in the many instances of breakage - the tongue itself could not move relative to the cabin piece to which it was affixed - the instruction meant to move the whole cabin piece backwards relative to the carriage, leftwards in the diagram! Unfortunately the cabin piece can be very reluctant to move.
This puzzle has a very nice motion of the green "step" piece that functions as a lock - it really does "rotate" outwards and downwards to the side of the carriage, but only after the first step of moving the cabin bottom / tongue piece backwards to unlock the step piece itself. In the image of the pieces, one can see how the floor of the cabin piece, over which the step piece slides, is rounded.

Hi-Way Patrol (or Motorcycle Cop) keychain puzzle, issued by Lional Plastics Corp. of New York. Seven examples.

Peter Pan Speed Cop
Same architecture as Hi-Way Patrol, but smaller - see comparison photo.
Speed cop is on bottom.

This instance of the Motorcyclist was issued by Bell UK.
The colors are characteristic of Bell keychain puzzles.

Motorcycle from Japanese "Puzzle Pet" set

Several examples of the Nu-Car sedan keychain puzzle issued by Plas-Trix 1949.
Also known as the Winner Stock Car, issued by Pal Plastics Inc. of New York.
The Nu-Car included a "license plate" that fit flat beneath the car, held on by slots in the wheels.

I found a Nu-Car with its plastic license plate intact, as well as an example with an intact paper license, and several examples on cards from Knight.

Card front and back, and paper instruction sheet.

The Winner Stock Car version - Pal Plastics

Here is the Bell version of the Nu-Car puzzle, on an original card.

"Mechanical Servants Car"
Six examples of a Sedan type of car. This one has a neat mechanism I like - see the rotation in step 4.
The first red and green example is soft plastic and the others are hard plastic.
Pussy of Germany produced a version as well.

Sedan keychain puzzle by Pussy of Germany
The chassis piece has "DBGM" and a logo.

The Sedan in Russian packaging.
(I traded the white so don't have it any more.)

I found another Russian Sedan - this one is pink. The package was not sealed, so I scanned the instruction sheet.

Five examples of the Jericho Car keychain puzzle.
I found an original instruction sheet (actually on cardstock, not paper). It shows that this puzzle was issued by the Jericho Corp. of NY - hence its informal name. They called it simply the "Mystery Automobile Puzzle" however.

Race Car or Racing Car keychain puzzle
"Speedway Racer" - Lional
(In pic of 3, ends are Lional center is HK - note wheels and Lional's rounded cowl)

Old Fashioned Car (Open Touring Car) - Lional - four examples

Here is an F1 race car keychain puzzle - Japan
#330 on p55 in the Compendium 2nd Ed.

Lotus Race Car - Japan
This is the same design as the #330 car shown above.
This car is also included in the "Puzzle Corner" set of three puzzles, shown below, that includes instructions on the back, also shown.

This is a large version of the Lotus Race car.
This is too large to qualify as a true keychain puzzle, but I include it here to show how it is the same architecture as the smaller keychain version.
It is made from some nice brightly colored translucent plastic.
Note the "Lacing Car" label.

This Race Car puzzle is from Japan
It is #334 on p56 in the Compendium 2nd Ed.
Two examples shown.

No. 6 Race Car - Japan
Appears in the 2nd Ed. Compendium as #335 on p56 "Race Car 7."
The card identifies this as a Porsche Carrera.

Porsche Carrera keychain puzzle - Japan
This appears in the 2nd Ed. Compendium as #312 on p52 "Ferrari" -
but the card accompanying my copy clearly identifies this as a ポルシェカレラ Porsche Carrera.
I think the flowing lines on this little model are very nicely done!

The Compendium 2nd. Ed. identifies this as the Spectrum Patrol Car,
from the 1960s TV series "Captain Scarlet and the Mysterons."
It is #348 on page 58. My example was included in a "Head Sports" set of five puzzles issued in Japan.
Hard plastic. Rubber tires.

This appears as #313 on page 53 on the Compendium, where it is called "Futuristic Car."
However, the original card identifies this as 宇宙サンダー カー which means "Space Thunder Car"

R-381 Race Car - Japan - from a Japanese set of three puzzles
#331 on page 56 of the Compendium 2nd. Ed.

This Race Car is slightly different from R-381
with a solid cowl and shorter side pieces, and no rearview mirror.
In the Compendium 2nd Ed. as "Race Car 4" - #332 on p56

A diminutive supercar (looks like a Lamborghini Countach) from Japan
I think my example is missing a rear wing.

The French company CIJ - Compagnie Industrielle du Jouet (or "Manufacturing Company of Toys") produced several small plastic puzzles or construction toys. They include a nice interlocking model of the Renault Dauphine car, which was issued in four different solid colors including light blue, white, red, and dark blue. They are usually found loose, but a 3-pack bag was issued that included the light blue, white, and red versions. I found a copy of each, including the 3-pack.

I was provided with a photo of an excerpt from the 2006 book Les Jouets En Zamac C I J & J. R. D. Automobiles Utilitaires Les Carnets Du Collectionneur by Thierry Redempt and Pierre Ferrer, that would seem to address the question of what different puzzles may have been issued by CIJ. The header cards on the bagged puzzles have confusing numbering.

According to the book (paraphrasing) "Although plastic molds, we decided to integrate the small AUTO-PUZZLE in this edition. They are delivered in a small bag with a stapled label. A 3-pack of the Renault Dauphine included blue, white, and red versions together. There is a fourth in navy blue. Similarly, there is a Renault brand orange farm tractor. The other two are the Renault Florida known in blue and light green, and the Peugeot 404 known in red and black with wheels, sometimes white, sometimes black or both mixed."

I received a photo of a carousel showing that the Floride was issued in (at least) five colors including red, white, lime green, dark green, and dark blue. I have also seen the Floride in light blue, and the 404 in yellow. However, the various colors aside, I know of no other models beyond the Renault Dauphine, the Renault Floride, the Peugeot 404, and the Renault Tractor.

Keychain Renault Dauphine - two examples

Renault Dauphine - Blue
I found a rare blue version -
Unfortunately the top was cracked in half down the center, but I superglued it.

I found another dark blue example, intact:

I found an example of the Renault Dauphine in Light Blue

Renault Floride miniature puzzle - CIJ France
This one is pretty rare - and even though it is not really an interlocking keychain puzzle, most collections allow it.
I found the bagged example, then two loose examples.

Peugeot 404 from the French company CIJ
Probably too big to qualify as a keychain puzzle,
but this is one of several puzzle vehicles issued by CIJ and it is fairly rare.

A trio of Keychain Volkswagen (VW) Beetles
I have an instruction sheet from the German company Pussycat.

Hot Rod keychain puzzle - Lido - four examples
along with examples of the instruction sheet and a card.

Merit Racing Car Keychain puzzle

A mini race car. I found several examples including one in a capsule.
One type has a number on the cowl (I am aware of different numbers appearing,
though I have examples only with '1'), another lacks any number.
Both types say "Hong Kong" on the bottom.

Mini Race Car, with original capsule and instructions:

Keychain Puzzle Jalopy or Touring Car - six examples

A larger version of the Touring Car - Japan
I found an example in gold in its package, and a colorful example loose.

The headlights are factory installed with the rounded sides facing forwards.

I found an example of the translucent version, too.


Sportster - hard plastic - Japan
Listed in the Compendium 2nd Ed. as Roadster 1 No. 338 page 57.
My copy is missing its headlights and crank.

Town Car - hard plastic - Japan
Listed in the Compendium 2nd Ed. as Roadster 2 No. 339 page 57.

Keychain interlocking puzzle car (Germany)

A keychain push-fit Jalopy, from Germany.
Not really interlocking, but I've seen it accompany other keychain puzzles.

A Puzzle Taxi - Japan (Maruka) マルカ

I found an example in its package on a card:

At the Motor Pool!
Keychain puzzle Jeep - smaller type with windshield up - 1949
7 examples
This is "Jeep 1" in the Compendium 2nd Ed. #317 on p53.
The Compendium also lists this model with the card I have as "Jeep 4" #322 on p54.
They are the same puzzle.

Hard Plastic, windshield down Jeep from Merit of England, with card.
The green piece says "Made in England."
This is "Jeep 2" in the Compendium 2nd Ed. #319,320 on p54.

Keychain Jeep - larger type with windshield down - hard plastic
Red, white, & blue version is from Kiem set.
Additional example was modified by a previous owner to insert a keyring.
These are further examples of the "Jeep 2" type.

Soft plastic large Jeep example from Hong Kong, in package
The soft plastic version has been issued by several brands, including in the Jig-Toys series. It is listed in the Compendium 2nd Ed. as
"Jeep 3" #321 on p54.

Soft plastic version of large Jeep with windshield down
several Jig-Toy examples

Soft plastic version of large Jeep - slightly smaller version, poor fit, loop on back.
See comparison with blue Jig-Toy Jeep.
The Jig-Toy versions do not have the loop on the back, so there are at least two types of the soft plastic Jeep.
The image of the soft plastic "Jeep 3" in the Compendium does not appear to have a loop on the back, however, the larger Jeep shown for comparison in the photo for "Jeep 5 - Mini" does have a loop on the back, and also displays the very poor fit of my example here.
I would say that the Compendium made no distinction between the looped and loopless versions of the soft plastic Jeep.

This miniature version of the windshield-down Jeep was included in a set of three miniature puzzles (Jeep, Field Gun, Destroyer) issued in Hong Kong. Hard plastic, and very tiny!
This is listed in the Compendium 2nd Ed. as "Jeep 5 - Mini" #323 on p54.

Going in the opposite direction from the miniature Jeep, this Japanese "Patrol Jeep" puzzle is almost too large to qualify as a true keychain puzzle, although it is included in the Compendium 2nd Edition as "Jeep 6" #324 on page 54.

Jeep puzzle - Japan (Ito)
パトロールジープ - means Patrol Jeep

This jeep version is listed in the Compendium 2nd Ed. as "Jeep 7" #325 on p55.
I obtained my example as part of a "Head Sports" set from Japan.

Fire Truck / Fire Engine / Fire Chief keychain puzzles - Lional 1955?

The fire helmet is not a puzzle, but sometimes accompanies the truck.

Keychain Fire Engine - Bell UK

Keychain Fire Truck / Fire Engine / Fire Chief with Siren - 2 examples

A Fire Truck / Fire Engine / Fire Chief - sealed in its package - issued by Knight Novelty
Note that even in the package this is missing its driver/siren piece.
Also note the instructions on the back of the package.

This version of the Fire Truck keychain puzzle came from Russia (from a seller in the Ukraine).
Note how they solved the problem of the frequently-missing driver/siren piece -
they simply eliminated it - see the closeup photo of the cab, which has no socket.
Two examples - one in its package with original instruction card.

Kottage Kar (Ice Cream Truck) keychain puzzle - four examples

Mechanical Servants Truck - two examples

Keychain Covered Truck - four examples
one by Mechanical Servants with package.
The two trucks shown on the left in the photo of four are missing their canvas bed covers. I am told this style of truck was always produced with a canvas cover over the bed; folks often sell or buy the puzzle and don't even realize the cover is missing (as I did).

Mechanical Servants Dump Truck

Keychain Dumptruck - four examples

The David Brown Tractor by Randall/Merit 1954, with original card - two examples

Six hard plastic Tractor keychains, with packages

Soft plastic Tractor keychain

I obtained a store card that has wonderful graphics, and instructions:

A locomotive from Japan, in its package.
In the 2015 Compendium this is #381 on page 64.
I obtained a second example in a bag.

The card identifies this as 弁慶号, "Benkei."
According to Japanese puzzle collector Naoaki Takashima, the original of the steam locomotive named Benkei
was made by Porter, Pittsburg, PA and imported to Japan in 1880 with other locomotives of the same type.
Further research identifies this as a JGR Class 7100, first used in Hokkaido. See Wikipedia.
It is still operable and preserved in Kyoto as in the photo shown below.

A Train Set from Japan - includes a Benkei style locomotive and two passenger cars.

Locomotive on card - Japan
This is "Locomotive #13" in the Compendium - #389/390 on page 65
新幹線 ひかり means Shinkansen Hikari (train) - the famous Bullet Train.

Locomotive set - Kabaya Leaf Japan
Details on these four puzzles below.
Also shown with two other types of locomotive keychain puzzle for comparison.

Locomotive (soft plastic) - from Kabaya Leaf of Japan
Listed in the Compendium 2nd Ed. as Locomotive 09, No. 385 on page 65.

Another type of vintage Locomotive, in soft plastic - from Kabaya Leaf of Japan
Listed in the Compendium 2nd Ed. as Locomotive 12, No. 388 on page 65.

A third type of vintage locomotive - No. 387 on page 65 in the Compendium. Kabaya Leaf Japan
Two examples.

A more modern Locomotive, in soft plastic - from Kabaya Leaf of Japan
Listed in the Compendium 2nd Ed. as Locomotive 10, No. 386 on page 65.

Electric Tram (Trolley) - Japan

ちんちん transliterates as "chinchin" and means tinkle, jingle, or whistle
電車 means "electric train"
コーナー means "corner"
説明図 means "explanatory drawing"

Keychain Boats/Ships

Examples of the Showboat (aka Ferry) - a flotilla!
By Lional, also leftmost two are HK repros.
The chain eyelet is smaller on the HK examples.
Lional is molded on the bottom on Lional examples.

Show Boat - Peter Pan UK with original card

Ferryboat - Bell UK with original card

The Mini Ferryboat or Mini Showboat - five examples
Shown in comparison with a regular-sized Lional Ferryboat.

I found one in a capsule, with instruction sheet.

Closeups shown below of two different Hong Kong markings - on the hull (left) versus the eyelet (right):

Cruise Ship keychain puzzle - five examples (but I traded one away).
Soft plastic.
They are all marked "CHINA" (with a backwards 'N') on the bottom.

Cruise Ship keychain puzzle - Put & Take Apart version - Hong Kong.
Many examples.
This version has no printing on the bottom.

Cruise Ship - Kabaya Leaf Japan
This version has no loop on the stack, and its pieces are far more precisely made.

A comparison of three versions of the Cruise Ship puzzle.

Above, four P&T on the left, four CHINA on the right, and one KL center.
Below, top to bottom in the first image, CHINA has orange stack, P&T has red, and KL has white stack.

Note that on the Kabaya-Leaf version, aside from the absence of the loop, the bridge is not as tall,
the aft deck is shorter, and the detail on the foredeck is sharper.

Here are the pieces of the three versions.

Destroyer - Merit 1954 - two examples.
Hard plastic.

Keychain Battleship - no brand noted. Three examples.
Hard plastic, same construction as Merit Destroyer.
Hole for chain in tail.

This miniature version of the Destroyer puzzle is part of a set of three miniature puzzles (Destroyer, Field Gun, Jeep) issued in Hong Kong.

Keychain Battleship - alt. version
Hard plastic
Note: rounded bridge, and simplified tail.

Keychain Battleship - another alt. version
Soft plastic
Note: small stack, loop at back

Steamboat - Bell (UK) - designed in 1952 by John Flower for Bell
Hard plastic.
This puzzle is very difficult to [dis]assemble because it fits too tightly and relies
on flexing the deck pieces. The soft plastic Hong Kong versions are easier to manipulate.
The open-sided deck piece is fragile and is broken at its narrow side in my copy.
I am not surprised the Bell version is rare.

Ship keychain puzzle - with package, made in HK
Soft plastic. Two examples.
This design had also been issued by Bell and called the Steamboat.
I have also seen it called the Cargo Boat.

Examples of the soft plastic Steamboat / Cargo Boat / Liner
(One incomplete.)

"Action Puzzle Toy - Ship" - another soft plastic version of the Liner.

Liner - Japan
Three examples.
Note that the instructions relate to the traditional Liner assembly but are incorrect for this much simpler puzzle.

Keychain Ship (pink) - soft plastic

Keychain Sailboats - soft plastic

This sailboat version came from Japan
The lack of loop on the main sail piece is characteristic of the Kabaya Leaf Japan version
However, the boat body is not correct - this appears to be a "Frankenstein" using the bottom two pieces of the Cruise Ship.

This is a correct example of the Kabaya Leaf Sailboat - Kabaya Leaf Japan

I found another:

Missile Boat from Japanese "Puzzle Pet" set

ジュニア means "Junior"
フライング means "Flying"
ジヤツク号 means "Jack"

An "invisible" Submarine - from Junior of Japan

Keychain Flying Machines

Jet Airplane keychain - two loose examples - Pal Plastics?
Also an unassembled example in its package, and a filled store card by Knight Toy and Novelty Inc.

Five examples of the "Atomic Jet Puzzle Plane" aka "Mystic Jet Puzzle Plane" - Champion Plastics Corp. 1949
Note the rounded wingtips and chain attachment loop.
The wings say "JET 1148"

This is the Atomic Bomber Puzzle Keychain issued by Toy-Trix 1951
(See Compendium 2nd Ed. Appendix #41)
I found a store card with some puzzles and instruction sheets still attached.

Note the oval-shaped, pointed wingtips and hole in the wing for the chain.
The tail has "USA" in raised letters on it.

Four examples - two with a one-piece fuselage+tail (shown first, with red and yellow tails),
and two with two pieces (blue tails) - see below for details.

Here is a comparison of a separate-tail type Atomic Bomber with the "JET 1148"

Shown below, instructions I found show the "LOCK" piece and the characteristic oval wing and body pieces, but note the fused tail.

As depicted in the pink instruction sheet, here is the alternative body piece for the Atomic Bomber puzzle -
incorporating the usually separate vertical rudder into the fuselage's central piece.

Below is a comparison - one with the one-piece fuselage with tail, and the other with a separate tail.

Another variant of the Atomic Jet airplane keychain puzzle with a smaller, pointed wing having "JET PLANE" embossed on it. Three examples.

Plane - Bell UK
Same architecture as the Jet 1148, but note here the wing is unmarked.

Keychain Jet Fighter - Merit (hard plastic) 1954

Originally, I found the "Jet Fighter" in soft plastic.
To me, it looks more like a bomber than a fighter.

I found a soft plastic version in yellow, too.

Here is a version of the Jet Fighter in hard plastic that features a pilot!

Another version of the Jet Fighter design, but this Hong Kong package shows a more likely image (IMHO) of a passenger prop.
Two examples.

Russian IL-62 keychain puzzle jet airplane - two examples

Russian "Boing" Airplane puzzle

I found an incomplete instance of a Jumbo Jet puzzle from Japan.
Sadly, it is missing five pieces of the nose, and the undercarriage piece is damaged. Still, an interesting find!
In the Compendium 2nd Edition as "Airplane 8" #433 on page 73.
With no scale shown, it was difficult to tell how small this puzzle is until I received the pieces.

I obtained a complete example, shown below.

Since this puzzle is both rare and fragile, I have taken photos of the disassembly sequence. In particular where the bottom main fuselage piece narrows and joins the bottom tail piece, both of my examples arrived exhibiting damage - a tiny tongue of the main piece fits into a slot on the tail piece and is too easily cracked off. However, this does not overly compromise structural integrity.

The first step in disassembly is to turn the plane over and poke upwards the small rectangular tab towards the tail, as an assist in lifting out the upper fuselage end (the removed blue piece here). This is tight, and will stress the fragile joint mentioned above, so be careful.

With the fuselage end removed, the top part of the next forward section (green here) can be slid backwards. Then, the roof of the forward cabin can be slid backward (white here). Both movements will be tight.

With the roof moved back, the roof (white) and windshield (red) part of the cabin can be removed upwards - there are two tabs below, holding the top on via friction - again, this move will be tight. After the roof and windshield pieces are removed, they can be carefully separated - don't damage the hook in the roof piece. Now remove the main cabin block (red here).

The top (green) part of the overwing cabin can now be slid forward and removed from its underlying (white) piece - it holds on via a kind of tongue-in-groove. The nosecone comprises two pieces and is attached to the bottom main fuselage by a similar kind of tongue-in-groove. Move the nosecone down and off. The bottom (white) part of the overwing cabin can be slid backwards and then removed upwards - it has a forward-facing hook that juts down through loops in both the upper tail piece (green) and the main wing (yellow). Here again be careful of that fragile hook and patient with a tight fit.

The two pieces of the nosecone can be separated - the lower has a tab that pulls out of a socket in the upper. The upper tail piece (green) can be slid forward, up, and off the lower tail piece (blue), which has a forward-facing hook that just up through a loop in the upper tail piece. Once the upper tail piece is removed, the rudder can be slid backwards and removed upwards - this is tight. Finally, if the bottom main fuselage remains unbroken, it can be separated from the bottom tail piece - or they just fall apart.

Keychain F-86D - ODK Japan - Odaka Sanyo (Odaka Industries)

Keychain F-104 - ODK Japan - Odaka Sanyo (Odaka Industries)

Airplane ("Fat Airplane") a.k.a. Aeroplane - five examples

In Japan, this airplane is known as the "Zerosen" or Zero.
ゼロセン translates as "Zerosen." The example below is from a Japanese set of three puzzles, as are the instructions on yellow card.

The instruction sheet below accompanied a loose high-quality example from Japan.

Here is a comparison of three Zero examples - one from Hong Kong (green), one from the Japanese set of three (yellow cockpit), and one loose example from Japan that came with the instruction sheet above (black cockpit). The latter seems to me to be of the highest quality of the three. Both Japanese versions have a keyed separate cockpit piece, separate wing pieces, a keyed propeller shaft, and a two-part tail cone. The Japanese versions are almost identical except that the version from the set has a hollowed-out tail piece. The Hong Kong version is so emblazoned on its tail.

Puzzles from Mechanical Servants

According to Bloomberg: Mechanical Servants, LLC was founded in 1946 and based in Melrose Park, Illinois. According to an old Wiki entry: Mechanical Servants was incorporated in 1955 by Harold Baum under the name Mechanical Servants, Inc. The company originally focused on manufacturing mechanical vending machines and providing the products to be sold. In the late 1980s, the company shifted its focus from vending to traditional retail outlets by changing its packaging, and offering its products in a blister packed format. On March 3, 2015 it was announced that Cleveland-based private equity group Weinberg Capital Group had acquired Convenience Valet and its parent Mechanical Servants, LLC.

Puzzles from Kabaya Leaf of Japan
カバヤビッグリーグガムパズル (Kabaya Big League Gum Puzzle)

The Japanese company Kabaya, in partnership with the American company Leaf, produced Big League Chewing Gum and a large number of small plastic puzzles, many of them interlocking, to accompany the gum as "bonus" or "extra" premiums.

While boxes can occasionally be found, there were few solution sheets or cards available.

As far as I know, there is no official definitive list of all the puzzles issued, even at the Kabaya corporate website.

The list below has been compiled with the kind help of keychain puzzle expert William Waite. The page numbers (pnnn) and item numbers (#nnn) refer to listings in the Compendium 2nd Ed. '**' means I do not have an example.

"Gray Area" and Non-Puzzle Keychains

Keychain Owls A group of simple Owl keychain "puzzles"
One "Nite Owl" in its package

Mini 2-Piece Owl Keychain Puzzles

Tiger - very simple, similar to the Owl
Two examples, one in original package

Three examples of a Two-Piece Fish - similar to the Owl and the Tiger.

The 2-piece fish was patented in 1958 by Olson - 2840878

Keychain two-piece Good Luck Clover in Horseshoe
Cites the Olson patent.

Keychain two-piece Bull Head
My brown example is very beat up, with one ear missing. The back of the brown piece says "5 5 75" so this might date from 1975.
The red example's white insert has several areas of raised text including "St Paul Minn USA" and "Remembrance." It cites the Olson Patent 2840878.

Yellow Pages keychain
Another very simple two-piece design.
Seems like it was intended to hide a quarter - but unfortunately it was made with an internal rib down the middle which prevents this.

A simple 2-piece advertising keychain.

A Rude Clown - not a puzzle.
Push in the button on the back of his head and he sticks out his tongue and nose.
Parts of a broken one shown sans spring.

Another version of the Rude Clown - a Rude Professor - Lindex
Wearing a mortar board hat embossed "Collegiate Cap & Gown Co."
Reminds me of the iconic photo of Einstein sticking out his tongue.

Jerry Mahoney - the dummy popularized by ventriloquist Paul Winchell in the 1950s.
This keychain toy allows you to move the eyes and the mouth using a protruding knob.

Clown Magic Coin Carrier - Lindex
This novelty keychain accepts small coins and can eject them via its mouth when you actuate a lever on the back.

Egg-Laying Duck
This keychain toy duck releases a small egg through a hole in its base when you push a spring-loaded button on its side.

"Don't Gamble" Die keychain puzzle
Only two pieces - almost a secret opening box.
Included in the 1st ed. of the Compendium but gone from the 2nd.

I found a second instance of the Don't Gamble die, in black. This one contained a surprise! Can you guess what it is - hint: it is in keeping with the theme "Don't gamble!"

Here is an example in pink:

Mini 3D Crystal Puzzles - Blue Heart, Pink Heart, Blue Slipper, Red Star, Blue Star
The Compendium 2nd Ed. excludes these since these are intended to lock permanently together and not allow disassembly / re-assembly.

Japanese Steamroller puzzle
(Too big to be a keychain)

Japanese Batmobile puzzle
(Too big to be a keychain)

I found this store card - the car is a transparent version of the "Batmobile" shown above, but here it is called a "Can-Am" racing car.

An interlocking puzzle Camera Spy Gun from Japan.

A Bug-Eyed Alien from Japan.

A metal Robot - Japan

A sort of Totem figure - known as "Patch Man" - Japan
Part of a series of several different designs, maybe issued in the 1980's.
Press-fit, not interlocking.

Another Patchwork Man (Patchy Man) from Japan
This ghost-like figure is evidently modeled on clay figures found on ancient graves - see this photo from a blog post on
These figures date from the "Kofun Period" (古墳時代).
I found a reference to "Haniwa" (ハニワ) - but that term also refers to a modern pop group and anime.
To me this figure probably represents a kind of soldier or knight in a protective helmet.

Ganesha Patch Man (ガネーシャ つぎはぎマン)

A series of small totemic figures - known as "Patch Man" (つぎはぎマン) - were issued in Japan, probably in the 1980's.
They are press-fit, not interlocking. Many consist of six pieces.
I have managed to acquire only a couple but I've created the catalog below for reference, based on images I've snagged from the web. AFAIK there are twelve different figures, but each can appear in several different colors, and some I have seen are multi-colored.
They seem to be based on iconic mythic figues or gods from various ancient civilizations.
I've given them silly names below just to name them something - maybe at some point I'll figure out what each is meant to represent.

Arc Hat

Baguette Ears

Easter Island Moai

Hindu Ganesha

Cannon / Field Gun - Japan
キャノン means "cannon"
 砲  means "cannon" or "gun"
分解説明図 means "exploded view"

Missile Car - Japan
宇宙 ミサイル カー - means "Space Missile Car"
のはずしかた means roughly "How to disassemble"
Comes with keys for the internal windup motor, and a spring-loaded missile.
When the motor is wound, the missile can be locked on the launcher.
When the car runs and the motor's spring unwinds, it releases the launcher catch and fires the missile. Cool!

A pair of Tanks, in package - Japan

新三共胃腸薬 means "Shin Sankyo Gastrointestinal Medicine"

A push-fit Locomotive - Sankyo Japan

A large Locomotive on card - Japan

An Articulated Fish - purportedly issued by Kabaya Leaf Japan

A push-fit Race Car from Glico Japan
Glico issued many small toys as prizes or "Bonus" items accompanying candy.

I found these two versions of a Helicopter (two examples of one type), made in Hong Kong.
Small enough to qualify as a keychain puzzle, but not really interlocking.

Viking, Atalanta, and Viscount Airplane puzzles
U.K. cereal-box prizes

A Rocket and Gantry - Japan

Puzzle Watch set - Japan

Reiss issued a series of small plastic vehicle construction toys or interlocking puzzles in the 1970's. They are a bit too large IMHO to count as true keychain puzzles, but some collections include them.

Classic Train Puzzle - Victoria - Reiss

Here is a section containing small images of just the fronts of the more colorful cards. Aren't they attractive?
