all four are marked "cherry" which I think are the manufacturer
2 have "E53" on the side, three tabs, est. 3 inch bent wire like for a coin switch
other 2 have " E53/F53" on the side, est. 3 inch bent wire like for a coin switch, three tabs and has writing on the top, "E53-60B" and 34-91
If someone told me these were coin switches it would make sense to me. don't know where they came from, I know I never bought them, may have come from another member when "Jeff not Jim' and I bought up all his stuff. Guess would be they are good or I wouldnt have such items but who knows?
All four I will trade for your completely refurbished KINGS & QUEENS or best offer or trade me anything or free , whatever. I have no use for them.
