I recently acquired a Williams 3 Coins that seems to be working and almost complete...except it is missing the moving target and motor in the center of the playfield. The motor is listed as 14-7740 on the schematic. Does anyone know someone that might have one available? Alternatively, since I'm still fairly new to motors, is there anyone that can get me more specifics about the motor itself? Voltage, RPM's, etc? It seems to the the same motor used on several other early 60's Williams machines that have moving targets as well. I've not had much luck beyond that. Could another motor model possibly be used instead?
