I had posted this as a wanted ad:

But this may be a more visible place. I need a score reel for my Williams Ten Pins. Nothing special about it, has a detent to trigger the switch to indicate when it is in the zero position (as opposed to using a reset coil), so I suspect any 5 1/2 diameter reel would work. Here is a picture of the good one from the player 1 side.
