    hi all, brought home this little project today

    hasn't run in a very long time....not only is the burner plate gone, but the cap gasket was just sand-like crumbles...have a spare msr dragonfly burner plate, if that doesn't fit will make one from brass......cap gasket will have to be cut from something safe

    That's gonna be sweet. My 71E is in my pack at the moment, one of my favorites!

    That’s a great stove!

    When you’re ready, it should make a fine entry in the Reference Gallery.


    Cheers

    Nice score. I do like combined cooksets/stove sets.

    disassembled, 1st stage clean, cleared jet with msr pricker, fabricated cap gasket and quick burner plate cut out of a scrap of galvanized tin (didn't have the msr dragonfly burner plate) reassembled (without inner the air adjust cup - until it's cleaned)

    preheat with some old hand sanitizer and a test boil

    love getting the "visible progress"

    still to do; clean the cotton strap + clasp, further brass + alloy cleaning, unkink the chain and of course make a better burner plate

    That's a nice find! I like these older primus stoves rather than the newer ones in the painted tin. I haven't found one yet but maybe someday.

    I don't know about the earlier Primus 71s. But the later ones used the same Flame Spreader as the Optimus 80 and Svea 123. The part may still be available from Base.Camp.UK. Cap gaskets are available from the Fettlebox, this site's sponsor.
    I do like the Primus 71E.

    This is an illustration from a 1937 catalog. The higher version L is the one you presented. The one on the left, on the other hand, is the one presented by the guy on YT in your other topic.
    I'm not an expert, but that's what it seems to me, judging by your photos and catalog illustrations.
    As for the burner plate. Seeing your capabilities, I'm sure you'll be able to reproduce a suitable replica from a piece of brass plate. 1713566009052945905069148587747.jpg

    thanks for that

    it says the 71K came with both 5" and 4" tall pots

    and the 71E pot only had the short 4" pot

    maybe only for the early years?

    as most of the later 71E pots seem to have the tall 5" pot

    That is the early small tank 71 - it seem to have been offered for about a couple of years beyond introduction of the tall 71, maybe a combination of surplus parts and a demand of short 71's to replace older Primus 70 out in the trails.

    Another option for NZ based stovies for parts is Keeping you out there | Caravan camping and marine They sell parts and gaskets for the old stoves including a burner plate for the Optimus 8r/Svea 123 etc. If the early 71s have the same size burner bell then it should fit.
    I'm fairly certain that the washer and seal kits they sell are the ones produced by the Fettlebox.
