I am restoring a Hi-Lo bagatelle game made by Automatic Games Co (ST.PAUL, MN). I am missing part of the mechanism used to bring balls to the plunger. There is a wood housing that is missing the wood knob that would turn the mechanism to feed the ball. There are two holes (top and bottom). Does anyone know what the part looks like? I have seen a later model from Automatic Games where the mechanism is inside the cabinet with an exterior knob that turns a wheel with top and bottom holes. On the exterior of the cabinet where the housing is attached there a two ball bearing push-ins (sorry don't know what they are called). They must have some function but not sure what.
I think I can make the part if I know what it looks like and how it functions.
Any information is appreciated -Thanks
