I would be interested in a set for my Gottlieb Picnic and Criss Cross from the late 1950s - can supply pix no worries.
You will need to keep this underground because of a certain pinball industry guy that thinks he is God. If you go public on this (eBay etc) he will jump up and down and act like a 3 year old and make all types of threats. If you want more info please PM me.
Good luck
