Matchbox Mustang No. 10 PISTON POPPER Made in England, 1973 This is a "Rollermatic" model with a gimmick that moves some of the body parts when it's rolled. This model is excellent, as the engine pistons move up and down in conjunction with the movement of the front wheels. The tires sometimes spin without gripping, making the movement sluggish. It has scratches and dirt because it was played with about 40 years ago. No box. Type of goods: Overseas manufacturer Scale: Other scale
