A Coleman 443, triple burner suitcase stove, aluminum case with red wings. No date stamp found, but apparently these, like their 'little' 2 burner sister the 442, were only produced for 1 year, 1963. Aluminum frame and wings are very thin, which contributes to her light-weight. Very attractive stove but takes up a lot of real-estate. For size comparison, on the right is the 2 burner model 442 and upfront an Optimus 22B. The 443 measures 7" x 28" x 14.5" or 2800 cubic inches (in cm: 18 x 71 x 37 = 47 250 cubic cm). Top view, with aforementioned stoves and one of Coleman's smallest 2 burners, the 6-J (Canadian Coleman). Like most Coleman double burners, the top lid is easily removable when not required (large pot, indoor range, no wind, etc). Unscrew the little bolt on the inside left panel. Pop out the pin on the right side. Outside view of the winged support holding pin that pops into frame side. Red Diamond hard plastic Coleman logo on outside top of front panel. Her thin but broad legs can be deployed when in use, a simple push out from inside of case and she sets in place. These give the stove a good 1.5" (2 cm) of clearance off the ground and decent stability. Double red angled wings supported by clothes hanger-like wire support are adjustable, but don't need to be deployed (user discretion). Both side burners' lighting and subsequent flame intensity controlled each by their own winged spindle, recessed just inside the frame (doesn't pull out) Upper right opening is the slot fitting for the wings' wire support. Between middle and right burners, on burner support frame, the model number 443. Manufactured by.. When packed up for transport or storage, the fuel tank is stowed under one of the 2 flip-up sturdy and heavy grates. Large surface area can support two camp ovens; a camp oven and pot; or 3 pots (stove is not lit). No priming required, just pump, turn the lever up as directed and light. After a minute, turn the lever down and start cooking. Thanks to the wide burn radius and fuel used (Coleman fuel) these output a lot of heat. After tea made, turned on the other 2 flanking burners. A great basecamping stove for large groups, ever dependable, simple, huge cooking area, great pot support, decent fuel volume, good wind protection, many cooking options, light for her size and very attractive. Some of her few negatives: size - this one is huge, so despite her relative weight it's not one to take canoeing or out on the trail without motorized support. Needs a large suitable flat surface to deploy, and best suited for large groups, car camping, basecamping and hunt camps. Like most >=2 burner Coleman stoves, when one or both of the non-primary burners are used the amount of fuel reaching the main burner is reduced and the flame suffers. But there's still adequate heat to cook (and/or bake) up anything required. Her fuel tank volume also suffers, it has less capacity than the 2 burner 442 due to the interior layout restriction caused by the primary burner's generator assembly. Regardless, it'll still sufficient to burn for a few hours before refueling is needed. Her aluminum body also is prone to dents and the little frame wings on her top lid are weak where they attach to the main stove's frame (easily bent).
