Hello
recently picked up a high top with the roll away escalator . My question is it seems to jam up a bit when pulling the handle down .It will shoot the nickel across the escalator at a high speed and then return back to the starting point . It appears to be hanging up on this part which looks severely worn to me . Does anyone know if this grind mark put on the escalator on purpose ? The grind mark referred to is just below the coin slider on the right hand side , it is where the brass is showing through the chrome it is almost like there are to separate but small humps that the slide catches on and jams up .
