I've got a 1950s Bally bingo where a previous owner removed the surround plates for the magic squares and coin slot for polishing. The plates look great, but when they went back on the game they were attached with phillips-head screws. I'd like to replace the phillips screws with original-style round head twist screws, often called escutcheon pins. I've been looking for the nails with no success. Has anyone found a source for new nails in the original shape and head dimensions?
