Steward Coffin design STC #39, with assembly jig #39A. All five assemblies require coordinate motion. Some are relatively easy; others are impossible without the use of the assembly jig. Allen made this for his exchange puzzle at IPP 21 in Tokyo in 2001.
The puzzle is complete in its original box from IPP21 with its original solution sheet and assembly jig. (The last picture is of the assembly jig.)
I
will ship within the US at insured priority mail pricing (around $10),
and am happy to ship overseas at cost, but I cannot always guarantee
that overseas packages can be insured. I will also consider alternate overseas shippers like DHL, who may be more efficient than the postal service.
Thank you for viewing my auction!
