You're probably better off....the internal mech might've been an original...the machine housing was probably a modern re-cast. And no key handy? LOL....did he tell you if it was an original key or a modern one???
If you're looking for a particular old slot, email me and I'd be happy to point you to a couple of (more or less)reputable sellers.
Old slots are a real "caveat emptor" business!
