John, It's worth noting here that the "Defense" notice with the photos of the NEW B 41 you posted (after this posting) says that NICKEL was THE reason why they changed their finishes, from nickel plate on brass to paint. Indeed, that stove has paint over brass. Coleman soon switched to painted steel. Because? The answer is that soon brass TOO was a defense item? OR that paint does not well stick to brass? My guess is that however hard it might be to paint brass it was harder for the Coleman folk to switch to steel (rust). Nickel shortage drove them to paint, THEN brass shortage drove them to steel. In this matter, I'd like better to know what the very early wartime use of nickel went for. I've just read Making the Atomic Bomb detailing how huge mounts of nickel were used in enriching uranium. But this did not start until '43. A Coleman is history in your hands.
