Rare yet Very cool lock puzzle! Satisfying solve!
Some info: Maybe not as hard as a Popplock, but certainly belongs in the Hanayama collection and reminiscent of some Hanayama puzzles designed by the prolific Vesa. Originally was an IPP32 exchange puzzle, goal is to remove the keys and (dis)assemble everything. https://ipp30.blogspot.com/2013/01/two-keys-lock.html
