Add to wishlist Details Original blank coin door used on upright arcade games made by Happ Controls. Outside dimensions are 11" x 8" with a 9/16" lip for mounting. We don't believe this door was ever used, it was found in its original packing bag. It does have a couple very small wear marks, overall still very nice and shiny though.
