My new acquired project, a 1941 B Coleman 500 stove. I passed this stove by 3 times, over a period of 2 weeks at a indoor flea market. It looked really terrible, not worth even the $13.50 that I paid for it. I could kick myself for not taking before pictures. I was really amazed that it cleaned up as well as it did. The bolts, nuts and fittings came loose easily. There was only a couple of specks of rust in the tank. I think this stove was used very little, then shelved for many years. It just looked bad.
