A customer comes in wanting some help rebuilding a "gun that was found on the beaches of Iwo Jima" by his dad. I'm pretty sure that wasn't the case, but I figured someone here might know what this really is, so here are a couple photos.
He honestly was disappointing that it wasn't used in the war, and even more so that it wasn't even a real gun, so I told him I would try to get some info on it for him, since his dad has passed already.
