Used but not for 50 years or more not tested as no key I have several keys I will look through later if I find one it will be included lock should be ok. I would refund if not no problem.
Key no is t0346 I think as it’s not the clearest to read. Missing one terminal connection screw.
Last picture shows a collection of keys I have for 60s 70s and a few later ones for Honda, Yamaha, Suzuki and a few Kawasaki give me your number I will look if you need one.

Any questions please ask.
