I recently obtained an AGM M1942 2-burner stove constructed in 1945. Same specifications as the Coleman 523, but some slight variations with the AGM-style burner knobs, check valve, and pump. All else is pretty much the same as the Coleman model, with the burner assemblies exactly the same as what is found on the single-burner M1941 (Coleman 520). I also found a case for it (AGM 1944) and the proper accessory wrench, but still looking for the proper windscreen. The stove was missing the burner knobs when I got it, but I was able to scrounge some spares from my parts bin. I'll add more photos as I fettle this stove some more. Today I just wanted to give the burners a good cleaning, place a new O ring in the filler cap, replace the pump leather, and light it up. The left burner looked like it had a leak in the past somewhere (paint missing, and scald marks on the decal). I disassembled and cleaned the burners thoroughly, and found that the left burner has an adjustment screw opposite the burner knob assembly, which caused a slow drip when burning. I was able to tighten it up, but now the left burner flame is markedly less. I'll need to see about re-opening that adjustment screw a bit without it leaking.
