Groetchen manufactured this 3 reel trade stimulator in 1940. This is one of the smallest trade stims ever made and has an award card flap that flips over the top of the reels to make it look more like a radio if the cops ever came by. It is in working condition but it could use a tune up. The coin won't drop freely and the reels jump into position rather than spin. The steel case has significant paint loss. One key is included. Condition (Good). Size 6-1/4"H. x 6"W. x 5-1/4"D.
