A Coleman Military Burner Model No. 527. This is another stove that I inherited from Grandfather, 15 years ago. The story I heard was that he purchased this new in 1945, from Montreal QC, at a military surplus store. When I obtained it she showed little if any use, although the box had been opened. It came with a military-green canvas pouch (unopened) of spare parts, a folding aluminum pot stand, key/multitool on chain, a small metal cylinder holding 2 spare vaporizers wrapped in cardboard and a paper Handbook (user manual) all packed into a wax-covered box (wax for environmental/water protection). Canvas pouch with parts: 2 sets of tie strings on the backside of it: The cardboard packing box wrapped in cheese-cloth soaked wax (covering the box's labeling stickers) Cloth Seam: Handbook (I'll post the book in the reference library). Number 12-43 printed on the front page, lower left perhaps indicative of the year (1943?) Model No. 527 parts list (part of Handbook): Fuel tank with operating instructions, spindle/multitool on chain afixed to fold-out stove support. The cut-out in the tool is used to tighten/unscrew the fuel cap: Single small burner bell/burner plate (can be unscrewed to access jet): Spare vaporizers/jet stored in cylinder under fuel tank, pump side. No rubber gasket on cap. Burner bell, fuel control valve stem, tip cleaner lever (all fully operational). COLEMAN on molding. Pump and fuel cap. Fuel cap with no rubber washer, just metal threads. Pump uses leather pump cup, different NRV system, standard Primus/Optimus style NRV removal tools will not work on this. No leaks in the pump chamber so had no need to access the valve. Stove and pot support in folded position. Pat No on opposite side of COLEMAN. Stove primed (with spirit) and running (coleman fuel). I didn't bother cooking up anything on it, not the most convenient stove for food prep. Flame shot patterns at night: 1/16th of a second. She has a nice purr when running, not overly loud like a Svea 123. Not the most practical stove for field-use: flimsy pot supports, no heat shield for tank, no safely pressure release, fuel control valve very low to the ground (need lots of clearance) making it a challenge to operate in all but flat surfaces, pump chamber overly large taking up lots of space in fuel tank, risk of metal seizing up (no gaskets), pump tube directly below fuel cap making filling without back-spilling a challenge, nice fireball occurs at every lighting (after priming), small priming well (fill the burner bell up to the first set of holes with spirit), no wind shield, etc. But she functioned well enough, put out lots of heat and i'm sure served her military duty well considering how many of these are around.
