Vintage Rabbit Hunt and Target Set

This is a 1960's Play Set From Marx Toys. There is a plastic shotgun that shoots darts, and a mechanical rabbit that you wind up and it runs around. The gun is approx. 23 5/8" long, and the rabbit is approx. 8 1/4" long. The rabbit works fine. I don't know if the gun works because it shoots rubber tipped darts, and there are none with the set. I pushed a thin dowl into the barrels, and there is spring action - the triggers seem to work ok. The box is in fairly good condition, but the cover comes off. See the pictures for more. This item is a plastic toy.
