Nice looking, quirky, Lilor Paris stove posted here for reference as there doesn't seem to be another. 1920s is only a guesstimate based on looks, others may know better. Three things stand out as particularly idiosyncratic: 1. Whilst the tank as seen is brass, the base piece is actually steel. 2. The burner seems to be roughly equivalent to a Primus No.4 burner, but has a much heavier top, fixed inner cap and features male threads on the bottom which are much coarser than Primus equivalents and non-compatible with other stoves. 3. The pump cup fitting is of a very crude non-floating variety. There is no flame-shot as I have decided not to risk damaging the tank. The reason being that there are areas of nascent stress cracking which may be discerned in several of the photos. There may be any one of several causes for this, stresses caused by differential expansion of the steel base, stresses resulting from the unfortunate crease on one side of the tank top, or simply issues with the original brass quality and manufacture.
Interesting stove, @igh371. Lilor pressures radiators also have brass tanks with steel bottoms. Cheers Tony
