It was either a commercial kart like you would see on the boardwalk or a race kart, I don't know. Its very solidly built with fat tubing, a solid axle and slick tires. There is no motor, sprockets, pedals or brakes (is set up for dual drums). It has two mounting plates for a Briggs type engine on both sides. This could be a good winter project for someone with the time to get all the parts it needs.
