Western Electric 7J
Western Electric 7J 5 cent prepay coin collector mounted on a special backboard with a Western Electric 653A antique hotel telephone. Together these create a 5 cent automatic prepay payphone. The user would lift the receiver, deposit a nickel (hear dial tone), dial desired number. If the call wasn't completed the coin would return. I actually have this phone hooked up with a coin controller and use it in my house.
