This is a beautiful Marx/Linemar ‘Junior Bulldozer’ battery operated construction toy in virtually unplayed with condition. It comes with the original driver, smoke stacks and headlights. Nice original box with inserts. Bulldozer operates on 2 ‘D’ cell batteries and has two electric motors that operate independently of each other. Switches are forward, stop and reverse configuration so that operating one engine forward and the other engine reverse makes the toy turn on it’s rubber tracks in realistic fashion. A great toy that I received from Santa when I was 6 . . . a LONG time ago! Nice collectible dozer.
