I wish I would have seen your message earlier, I just sold the Trapshoot PCB on Ebay for $20.00 including shipping. (I'm liquidating an old coin-op business, so I just list everything I find on Ebay for $.99 and see what it sells for)
Anyways, I know I do have a Trapshoot coin box that went with the board, it is probably in rough shape. I may have other parts for the game, if I find them I let you know.
If you are intersted in the coin box, I can post some pictures.
