    A primus No.1 with several bits of bad solder repair as usual. She runs well for one thats see a fair bit of action judging by the wear in the hole in the pump shaft cap.

    So, this would be stamped "U"? This would make it the final year with the old-style lower leg profile. From 1931 (I had thought it was 1930), the legs of these 1 and 5 models received the later "stepped" lower leg design. The top profile of the legs on the present (1930) stove are already less "extreme" in their curve than those from the 1920s and earlier.

    @abbahco1 Yes it’s U. I am slightly confused by your comment about the lower leg step? Mine does appear to have “stepped” legs?
    Thanks for your interest

    After 1930, Primus used this kind of leg.

    Primus No 5, 1930

    This one is also supposed to be from 1930. Compare the lower leg profile with that of your own stove. This leg profile remained through to 1964

    My stove is featured just before yours in the 'Gallery. I have the 'B' stamp indicating it is a 1912. You can compare leg profiles as they appear to be the original factory soldered legs.
    I wonder if you may be missing an inner burner cap as your outer cap appears red hot even in daylight.
    In the alternative, you could have an enlarged jet (or nipple) orifice as a result of normal cleaning over the years.
    My outer cap normally runs a visible blue flame with only the spaces between the holes and cap wire usually glowing red.
    I could be wrong about your stove wherein the whole cap should achieve a red hotness and perhaps those more expert could comment.
    Your Primus No.1 is a classic and I think the fettling will be as satisfactory as it was my own.
    Regards, Jaime.
