Here is my latest pride and joy! A 1948 Coleman Model 500 "Speedmaster". I found this at a flea market under a pile of Army surplus odds and ends. These stoves were supplied to the Canadian Army as part of a 5 Man Arctic tent kit. They were called "Stove C1B1" This one had no evidence of being used.I performed only a little cosmetic fettling to bring it back to near new condition. Not bad for 6 dollars! We used it on our summer canoe trips,including a week on the French River in northern Ontario(bottom photo). A search on the phrase "Stove C1B1" will bring you to the Canadian Army Arctic operations manual with operating and maintenance instructions for these units. When I was in the Army we had already switched to suitcase stoves so I was delighted to find this classic.
