These finger wheels are New Old stock (NOS) and made by Automatic Electric specifically for payphones. They are sturdier and have a factory hard chrome finish that less apt to be destroyed than the normal finish. This is a factory hard chrome finish that was used for payphones. They chromed these to take abuse. The finish is different than most chrome finishes.
Also, if you have a AE3 slot payphone with a plastic finger wheel, you can now replace it with one of these. Looks beautiful on an AE80 or AE40.
