Groechen IMP Trade Stimulator

This is a 1940's Groechen IMP Trade Stimulator that has been restored.
These are similar to slot machines in that they have three spinning reels. However, they have no payout and were thus legal in places where slots were not. This machine has cigarette label symbols on the reels.
During play, when three like brands lined up, the customer won their choice of a cigarette pack from the operator/store owner.
In addition, each penny play dispenses a gumball in order to maintain the appearance of no gambling. IMP has a metal flap which displays the reward payout and flips over the reels to reveal a radio dial printed on the other side making the machine look very much like a small radio to unknowing authorities.
