This is a 1952 Burmos 2 Pint silent burner. It was covered in very thick and poorly applied military "Olive-drab" paint which was awful! I stripped it back to brass and cleaned it. Even the pan ring was painted the same khaki colour. However, what I do like about these stoves, and they were also made for the military by Monitor, Thermidor and possibly Buflam, is the weight of the brass used and the wonderful idea of a removable pump shaft. This made repairs in the field much easier. Steve.
