Hello everyone, This is a stove I bought at a flea market; it was in relatively good condition. I assume it dates back to the early 1930s. All threads (pump, vent screw, filler cap) were seized for good ( it is not the reason for this inter-war dating ) Stamp on the bottom of the tank: The rest of the stamps: Trivet was original The filler was soldered many years ago, but the joint was tight. Details of the pump Works pretty well: Thanks for watching. Take care Stan
