Coffin’s Dilemma - Stewart Coffin Design #213-X by Pelikan - IPP 28 Prague Exchange by Abel Garcia

This puzzle was beautifully crafted from Ash and Maple by the Pelikan boys, Jakub and Jarda.

Here’s Stewart’s Description:

“Seven experimental interlocking dissections of a 4x4x3 rectangular solid come under this heading. 

All were made in contrasting fancy woods with symmetrical patterns on all six faces.”
