As an earlyish Hasag paraffin stove, this is the No.10 companion to the No.11 and No.25 models already present in the reference gallery. At roughly 1½ pint size, overall dimensions are similar to a Primus 100, although it has a smaller cast trivet size at only 8" diameter. Age/dating seems to be problematic, as one source claims use of the main base and tank top logo designs was 'pre-1903', whilst the standard pump cup assembly and lion feet design seems to me to suggest a later dating. 'Hugo Schneider Aktienges, Leipzig', translates as Hugo Schneider Stock Share Company, Leipzig. The iron trivet arrangement is quite unusual in that the upstand leg tops are simple outwardly directed 'L' shapes, which clip into semi-enclosed sockets in the cast top plate: The filler/pressure release cap is similarly idiosyncratic: The pump is more akin to that on the smaller Hasag 25 stove, than that on the larger No.11: Careful observers of the photos will have noticed that one of the original feet has long since gone missing, and has been replaced by a very crude, if functional, substitute. I'm still tempted to try to create a plaster mold off one of the good feet, then attempt to cast a better substitute in lead ... maybe. The burner is also clearly a later replacement too. The spelling of the cast name on the burner head, 'PATRIK', suggests a central European origin.
