I know absolutely nothing about these other than it's German and it's the first stove I have with feet like a lion? No tin matches this one in the gallery.... Looks really old. Losing pressure slowly... But working on it. From my awesome brother in law as a birthday gift... From Bratislava Slovakia found as is.
Hi @Remus1956 . I’m guessing this is from the interwar period (judging by the illustration on the cover of this catalog)https://classiccampstoves.com/threads/perfektus-stove-overview.28430/ . It’s true that the style of the filler cap with the vent is different, but it still fits that period. Maybe the illustration on the sides of the canister (which you didn’t show) will shed some light on the matter? By the way, this great article is worth reading: Ernst Hähnel - 50th Anniversary 1935
@Knee hello my friend! These are listing photos where he found it... I'm not home right now but I'll take even better tonight
