This is a very nice tin wind up tractor with driver by Gely of Germany.  The tractor measures 5" in length by 3 1/2" in height to the top of the driver's head.  The front wheels move via a lever on the front.  The wheels are marked "Dunlop Cord 7.00-18" and "Dunlop Cord 5.25-18".  I don't have the key but all wheels appear to be loose and functioning.  A great tin tractor.
