Pretty sure this is a 1015 coin grinder. I am sure but if not, someone will correct me. I bought this many years ago to go in a Mexican box that was missing the coin mech board, as they all are, but I never used it. Surface rust on the two sheet metal parts but as you can see the internal parts are nice and clean. This has not been around moisture. As I recall it was a working grinder but I'm sure it will need some light oiling. Take a look and ask any questions.
