Wondering why there would be wear in the "rod" that sticks out, sort of the stop for the shooting lever. The lever does not touch the metal rod, at least not now, although I haven't tried forcing the lever down that far (it might if you really yank down on the lever). Maybe the cushions behind the play field at one time were gone or totaly worn out? Or players back in the day would really want to shoot the ball that hard? My A is the old type where originally the balls would continue around the track, no bumper to stop the ball and bounce it back into the field, so the player were trying to see how many times the ball would go around the track before falling into the field or back to the shooting lane?
There is some serious wear to that rod which seems to match where the lever would contact it. (this is a single ball "A". What I am talking about "looks" like a stop bar from in front of the machine, the real stops are in back of course)
