Designer unknown, made by Eric Fuller.

Here is what Eric Fuller says:
"This 13 piece interlocking burr puzzle was published in the magazine
number 11 in 1926.
There are 2 possible solutions, both very similar. Despite its not being a high level puzzle,
the solution is surprisingly tricky, probably because of its unusual shape.
Ishino Keiichiro posted it on his site and Matti Linkola discovered the magazine."
