This is a rare puzzle by Stewart Coffin, his design #39. He invented this puzzle in 1983 and made it in wood, since then this puzzle become famous for two things. First, for the difficulty of making it accurately in wood, and second for the difficulty of assembly. Ironically, it seems the more accurately this puzzle is made, the harder it is to put together!
