Description
This is an exceptionally rare prototype of an already-rare Stewart Coffin puzzle! Numbered 101-A in Coffin's catalog of designs, Iso-Prism is an incredibly difficult cousin of the Twelve-Piece Separation. Coffin made no more than 8 "production" versions of this design, noting its difficulty to manufacture and assemble.

This unique piece is an early prototype of Iso-Prism, with many of Coffin's pencil markings. It is truly a puzzle for a Coffin lover to love!

This puzzle comes from the collection of the late Saul Bobroff, which we are selling on behalf of his widow, Paulette. 

Buyer to pay shipping, calculated after the auction.
