Bally pinball machine made around 1970 called Double Up.It is a Mystic line series,has advancing odds, odd even, half, corners, extra balls ABC moveable screen. This machine has been stored for many years but it works great. It has some surface rust on coin door&legs,some scratches on side, paint has faded with age but not bad.The relays,step up units& mixers show no wear,so this machine was used very little.I oiled the motors and wiper assemblys.We been playing for 2 weeks and no problems,lights&controls all work.Fun to play ,looks good
