Single burner stoves from American manufactures Coleman have been used by armies since WW2. Not sure if the model 533 was also in military service. The single burner stoves from Coleman like the 442 Feather and the 533 Sportster are nowadays very popular in the Motorcycle camping world. The ability to work on regular automotive fuel is what makes it the stove of choice. Although regular automotive fuel will wear out the stove, resulting in poor simmering control or a blocked generator tube, it is just too tempting for most bikers. White gas such as Coleman Fuel or Aspen 4T will ensure a longer life span of the stove while burning much cleaner.
Motor cycle blogger Stuart Fillingham made a very informative YouTube movie about the Coleman 533 Sportster stove.
Other advantages of the single burner stoves made by Coleman are that they can be lighted without pre-heating. Coleman has developed a fuel adjustment system in which the volatile vapors above the liquid are burned first and so serving as a pre-heating source. The burner in mounted permanently on top of the fuel tank. So leaking of fuel as you will encounter with stoves with a tank attached by a hose will not occur. The pot holders will accommodate small cups such as canteen cups but also much larger pans.
