Parts tube for the M1941, M1942, 520 and 523 military stoves.
Each contains a new vaporizer, gas tip, large packing, and 3 screens.
Information on these kits:
These tubes are probably from the WWII era. The model M1941 is another name for the 520. The military called it by both names but it slowly evolved into just being known by the 520.
The M1942 is a completely different stove. However, the generator would be the same as used on the 520. All the other parts in the part tube will not work on the M1942.
The 523 is a two burner stove. It is actually just two 520 stove valves and burners mounted on one tank. So all of the parts in the tube would be correct for the 523, but you would need 2 tubes for it.
