I did some research on the wheels. They are Ohio Rubber Company (ORCO). Out of the Northern part of Ohio. The rubber company used to manufacture lewisite a chemical ware fare agent during WW1 or WW2 when not making rubber tires. I have it all cleaned up and put on a white cloth covered gas hose and brass nozzle with a hook. What do you guys think this thing is worth. In Jacks book it lists $1,300.00 but I am sure that’s in mint condition.
