I found some little (maybe 3" tall) bowling pins that were made to light up and show which pins were knocked down on either a Ball Bowler or Shuffle Alley. Anyone have any idea what machine these "scoring pins" might be from or if there is any market for them used? I don't have them here at the house but I would guess they are about 3" tall with a pin number on each of them. I don't have a full set of them but I have several of them that looked pretty decent.
