Thanks to @Mackburner - I know now that this is a Kerosafe - no pricker= made between 1915-1920. Pics are from my shed during first take-off. The handle is Cast Iron and heavy. I use a standard Coleman pump, which fits fine. It had stress cracks which I sealed - As per advice from Neil/Mackburner I removed some ugly brown asbestos from inside the Generator and replaced it with some very fine brass mesh rolled up inside the Generator. Mantles are two old Coleman 21 Silklites.
