The light-up sign / marquee would look nice wired with an electrical cord & mounted on the wall, if it's in good shape. just a thought.
I had the same thought so the sign is was coming off. The coin mech is worth something as well. I haven't checked to see if it's a .75 mech or higher.
So fan motors and the thermostat it is. I may see if the helix motors come off easily. They could be the same for choice vends back to the 50's.
