My One and Only - Stewart Coffin Design #178-A by John Devost

This is another cool tray puzzle that I thought I’d make a copy of, woods used for the pieces are Redheart, Yellowheart, Zebrawood, Bocote, Black Palm, Bloodwood.

Tray is made from Peruvian Walnut with Yellowheart Slipfeathers.  Bottom is segmented Red Zebrawood and Peruvian Walnut (see note below).

Please note that there is a slight glue up flaw in the segmented bottom tray panel, it’s only cosmetic and does not affect the solve.  I have lowered the opening bid and it can be seen in the last photo.

Here’s Stewart’s description:

“I include this seemingly mundane puzzle design to show that there is still room for discovery within even this most common category of dissecting the plane - what I call “graph paper” puzzles. The problem here was to find a combination using the five non-symmetrical pentominoes (made of five joined squares) plus one other pentomino that fit into a rectangular tray one way only. After a long search, this goal was finally achieved.  Then, using an amazing computer program called 

PuzzleSolver3D, I had the satisfaction of confirming that I had discovered the one and only combination that met all of my requirements. Try to top that if you can.”

Shipping cost to be determined at close of auction.
