Vintage Coleman 500 camp stove single burner 1947. Underneath, you can read "Model No. 500 used generator #500-289". On the tank, it's punched "Coleman the sunshine of the night Made in Canada Trademark Regd. 47 --- 2". The colour is green painted on a brass tank. Now, as for the condition, 2 very small dents, a bit of rust, mainly on the ring on the contour, needs a good cleaning. The valves turn freely and the pump works good. Please note I haven't tried it with gas.
