Gottlieb 1954 'Double' games
On these games a second coin at the start doubles any replays won. One coin lights the thimble lamp on the lower arch; it goes out when the 10,000 unit first moves (or when the second coin goes in, which lights the backglass Double lamp). The credit unit has an extra coil and mechanism that adds two credits per step.
