As a wagon collector, I can honestly say I've never seen one of these until I bought this one. I still cannot find any information on it. I hate to toss the "rare" card, but I think this could really be a rare one. All metal, including metal wheel rims. I'd estimate 1970's era based on the wheel type and graphics. In good clean condition with a few paint chips and scrapes. No dents. Wheels spin freely and axle is straight. Tub inside is 20-3/4 x 10-3/4. Cute size to pull behind your wagon or pedal car!
