Not a price policeman.

Twin Bill, there were 800 made. One pinball guy gives it a high rating for game play. Remember condition is important. Other players have game rated this game in the high 7's.

Woodrails have gotten tough to price. Not as many collectors of that era as there used to be and they are somewhat under appreciated as players anyway. Twin Bill is a lower production game with a somewhat unusual dual scoring system. It’s been a desirable game in the past for woodrail collectors, I’d think about $750 +/-, more if it really floats your boat once you get a chance to check it out. Good luck!

Steve has new repro rails ($44, unfinished and need to be cut to length):
