I'm working on the interesting 44-note Auto-Electric coin piano, sold on eBay a couple months ago, which we speculate runs on 110 vdc. It uses an endless roll with a d.c. electric motor drive. It looks like a friction disc drives the roll, rather like what Wurlitzer used. The motor shaft is next to a drive disc made of leather sandwiched between metal plates. The d.c. motor is mounted so it slides left and right. The mystery to me is this: The motor shaft is missing whatever fit on it to drive the roll, and the motor shaft is so close to the leather disc (about 1/16"), I cannot see how it would work. Any ideas? Regards,
