Hi, I have a lock that I was told will work on some antique slot machine???? I never tried one in a machine so the price is much lower then you would expect. This is a ILLINOIS Lock made in the UNITED STATES. I’m selling this as a lock only buy it if you think it might work for you you might want to try it. I’m selling this as Old Stock never used for parts only and it might not work for your intended project.
