Hi, all. I just found this Ultimus stove in Norway, - it is very uncommon in my country. It is clearly marked No. 1, and there are no identical stoves in the Gallery. One from @Hazet is close: Ultimus No. 1 Both are No. 1 and have fixed legs and roarer burner. Mine is equipped with a windshield, which I doubt is original as this stove is primarily for indoor use? Mine also have older (?) type straight legs without "feet". The burners are not identical, as mine only says "ULTIMUS", but not "Made in France". Further, mine has a "square" air release screw. As I see an identical one at @igh371 stove: Ultimus No.0 Traveller c.1920? , I believe mine is original. My stove has a wrong filler cap. I find two different being used on the Ultimus stoves, and don't know which would be correct for mine? Anyway - the chance of finding any of these filler caps is pretty slim, I guess :-) Any additional info on date etc. is appreciated! Cheers, Håvard
