So it's not visible when the cube ...

23-piece puzzle by Bill Cutler from the collection of Dr. Benjamin Muckenhoupt. As Cutler describes it on his web site:Every dimension of every piece is different and there are no holes in the box. (The 23 pieces have 69 different lengths, widths and heights.) 23 pieces is the smallest number for which this can be done.Articles about this puzzle appeared in Scientific American and the Journal of Recreational Mathematics in 1979.Dr. Muckenhoupt often received early prototypes from Cutler, and the...

Original Cutler Cube, Type B, built by Bill Cutler for Dr. Benjamin Muckenhoupt. This is the cube Bill Cutler mentions in his monograph, "The Cutler Cube Puzzle," where he writes (p.5):Version 6 was designed around 1976, and the first models were sold to called "Type B").Cutler's first prototype Cubes are don't display the woodcraft of later, more polished Cubes. The piece ends are rough, and there are gaps between pieces visible in the photos. But this puzzle brought Dr. Muckenhoupt great joy....

Cuckoo Nest by Stewart Coffin (STC #21) built by Coffin ca. 1977 with original puzzle sheet, from the collection of Dr. Benjamin Muckenhoupt. There are two solutions. A previous Cubic Dissection lister wrote:"Stewart Coffin wrote in "Geometric Puzzle Design" that assembling a cluster of separate hexagonal sticks and dowels can be a puzzle but a more difficult and therefore more interesting puzzle will be made when some of the hexagonal sticks and dowels are joined to make elbow-shaped pieces. T...

It's hard to let it go but... Decided to sell this beauty to fund future Puzzle Wanderer content.The Flying Scotsman had a run of 50. This one is #40. The Hunter's dream.It's also monstrously challenging - in fact, so challenging that I had to use burr tools just to disassemble it, after 3 years of trying.Oof.Not only because of it's high assembly level, but also... ...well, you'll see. I don't want to spoil it.Hope it comes to good hands.Take care!
