Hello all, I recently acquired this Bally Mystic pinball game and behind the backglass there is an area, on the front side of the door that swings open, that has something that is missing and you can see the outline of what used to sit on the door in that spot, which is located right dead center of that door..... does anybody know what's supposed to be there, is it anything important, is it something that I should try to find or does it not matter at all? See my two attached pics and. In the pic that shows the backside of the backlash you can see the outline where something once rub through a little bit of the paint on the back glass?
