    Here is the Prince #100 I recently won. This is the as received condition and I will make a second post when the stove is properly fettled. This stove appears to have been Brasso'd nearly to death. That chalky residue is everywhere.

    They seemed to have their own convention for model numbers with most manufacturers 100's being the collapsible 'discus' type.

    Ross, this is a pretty good sized tank. The photo didn't show it but it has a lipstick tube burner, too. There was no reserve cap nor is there a place to store one. Nifty little feet, though.

    Hi Ross, I agree with you. The No.105 which KFE produced also has "square shoulders" rather than the discus -shape one might have expected if they had followed the same numbering convention as other Swedish manufacturers.
    I reckon this KFE 100-series, although collapsible, might have 2-pint tanks.
    Best Regards,
    Kerophile.

    Ross or George, can either of you make a guess at when this stove was made?

    Hi Sparky, My guess is the 1930s, or earlier, based on the "Mickey Mouse" ears on the filler cap and the lower position of the spirit-cap on your stove.
    Best Regards,
    Kerophile.

    Thanks very much, George. It now becomes an issue of whether to repair it to working condition and leave the patina or to restore it to like-new. No easy answer on one this old.

    Here is the Prince 100 mostly fettled. Still working on the NRV.

    Just for the record, I took the NRV out of a Monitor 51 which has the biggest fount in my collection, and tried it in the Prince. Too small. I can only hope I can loosen the pip holder in the one that came with it.

    OK, got the NRV to work but the burner does not seem to be functional. This does NOT look like a factory lipstick tube burner:

    French maker Lilor did a lipstick burner with removable nipple but I've not seen this in my KFE catalogues. I think you have a repair here - maybe by one of Presscall's ancestors? :lol:

    I thought it might be a repair because the nipple is slightly off center. If you look at the photo of the burner bell, the material surrounding the nipple becomes liquid when the stove is burning. It is probably just solder. Well, until I can find a replacement burner, she is a Shelf Queen.

    Ross, one more question: since it appears that this stove did NOT come with a lipstick tube burner from the factory, can I assume it probably came with a roarer burner?

    Sorry Bob - having just re-read my last reply I can see the ambiguity.

    Your stove DID come with a lipstick burner - it was the removable nipple that I haven't seen in the KFE catalogues. I'll try & get one added this weekend.

    If you wanted to fit a regular roarer burner you'd need a burner-to-tank boss, with a male thread of course.

    How about trying to get hold of a lipstick burner from a Primus or Optimus 100?

    I offered to repair Sparky's burner tube, using the technique I've developed of silbrazing an insert in the tip, equipped with a jet orifice of the right size (0.23 millimetres for both 96 and 100 series stoves).

    First I took stock of the components Sparky had sent me. The white stuff in the vapouriser tube was some sort of fire cement and I scraped it out to reveal a perfectly usable (once cleaned up) roll of gauze inside

    1318455512-IMGP4052.JPG


    I assume the cement was an attempt to make a tank-to-burner seal, but of course it wouldn't have done a particularly good job and bits must have constantly eroded, ending up blocking the jet. Beats me why the owner didn't simply use a new lead washer as the seal.

    Sparky was right, the jet nipple was a bodge. A tapped hole in the tip of the vapouriser took a conventional jet nipple (too big a size at 0.32 millimetres, so it must have run rich when it wasn't blocked with bits of fire cement).

    Tapping a hole in thin metal isn't a good idea and in an attempt to seal the inevitable fuel vapour leak, molten solder had been poured into the burner bell/vapouriser tip well. Can't have worked though

    First job was to clean up the tapped hole, getting rid of the residual threads and tapering the hole slightly to take the insert

    1318455606-IMGP4057.JPG


    Here's the insert ...

    1318455623-IMGP4058-1.JPG


    ... inserted and ready for silbrazing in place

    1318455639-IMGP4063.JPG


    Brazed up ...

    1318455655-IMGP4064.JPG


    ... and cleaned up

    1318455678-IMGP4093.JPG

    1318455690-IMGP4094.JPG


    The vapouriser fitted my Primus 100 so I was able to test fire it.


    Moderate flame setting ...

    ... simmer

    1318455769-IMGP4103.JPG


    ... high

    1318455785-IMGP4102.JPG


    Finally, I removed the flame plate and popped a Primus 100 converter cap in place in the burner bell

    1318455813-IMGP4104.JPG

    I'll pack the parts up and get them back to Sparky ...

    John, you are an artist, sir! :thumbup: :D/ :D/

    I did make a new lead washer out of a large fishing weight so I hope that solves any leaking problems.

    John, got the burner back today. Absolutely incredible! What a wonderful job of fixing a totally botched fettle! Thanks again! I will fire it up this weekend!

    Hopefully this thread will get reserected..


    I just picked up a Prince 100 this weekend and it has a lipstick burner with a removable nipple. Mine has a silent burner on it...but has the cut outs for a roarer plate. Looks to be the same era as this one.

    I have read this thread with interest and saw how John had repaired the lipstick burner for the Prince.
    Certainly an excellent idea and it works well.

    I have wondered whether an oversized hole in a 'Lipstick' burner could be filled by brazing over the hole then re-drilling it to the proper size again..
    Has anyone tried doing it that way?
