    Hi All,

    Here's a Primus 100 from 1924 - date code "N" - which came in it's own tin. I did not polish the tank as it's working on a nice patina. I cleaned the rest of stove , including the vapo tube , vapo tube guaze, inside of tank ( was really clean although ) and and anything else that needed cleaning. It came with both the OE flame plate and two-piece brass silencer , so glad to get an OE silencer :) :clap: Tin is a little rough , but hey it's 85 yeras old :)

    As you can see, I suspect the vapo tube oriface is slightly enlarged as the roarer flame is strong but shows yellow tips and the OE silencer flame is yellowish too. But when running the steel Primus silencers from BaseCamp, it seems to run pretty darn clean. Any thoughts you all ??

    I have ordered a new #100 vapo tube from BaseCamp just incase .

    Tom

    P.S. I have more pictures of the tin and close-ups of the OE silencer and flame plate , as well as the OE meths bottle. I will post these in a second round due to an overload here.

    Hi Tom, You have a lovely stove there!
    Regarding your question about burner apertures and yellow flames: I have found over the years, and again recently with Gary's silent dampers, that the silent caps tend to be much more tolerant of the richer mixture associated with an overisize aperture than are roarer type burners.
    I think there is greater burner area, and better air/fuel mixing, associated with the silent cap design and its multiple flames.
    I can only suggest thet there could be minor differences in design between the original, early brass damper, and the later steel damper sold by Base Camp.

    You could always peen the aperture of the lipstick of course.

    Best Regards,
    Kerophile.

    Wow! What a beauty. Very interesting that it has what seem to be Chinese characters on it. I'm used to seeing Arabic and such, but I don't recall seeing Chinese.

    The yellow tips perhaps is because of the difference metalurgical properties of the caps used. I believe that steel remains slightly hotter (or colder) than brass so there is an after burn resulting in yellow tips. But it really looks like a good flame.

    Hi Jim,

    I recall a thread here from around a year or so ago where it was determined there were some 13 or 14 different languages on one stove. This included both Chinese and Japanese. With the help of all the different members around the world I recall we identified all the different languages. Actually, I say "we", I don't recall that I would have been able to contribute an awful lot when it comes to foreign languages.....

    Cheers, Graham.

    Hi all,

    Thank you all for the nice comments.

    George , I just can't do the "peening", beyond my skills and just don't have the guts to try on this old vapo tube. I have taken the easy route and ordered a new #100 vapo tube from Mike at BC instead. :)

    Here are some more pics of the tin and the flame plate and silencer, and a few others

    The flame plate is rather crudely engraved compared to my later Primus 100 plate

    The OE brass silencer is a two piece design

    Well that should be enough pics I reckon

    Tom

    P.S.

    Anybody know what this is ? It was included in the kit, but Ihave no idea what it is ?

    It's made of steel and is painted on both sides a kinda' burgundy color

    Hello Tom, irrespective of what you have paid, I consider you fortunate to have acquired this seemingly complete and authentic stove set.
    Although, I do have some doubts about the windshield: it 'proclaims' Optimus and is remarkebly untarnished. But that meth's can is wonderful: these tall No.1739 cans are rare to begin with - contrary to the Optimus variety - and yours is a very rare gem indeed!

    Probabely (still) there because the set seems to have been used sparingly.
    Also, the flame pattern/colour does not seem to warrant a new lipstick, but I can understand that you want to 'cuddle' your baby!

    The reddish 'strip' I doubt has anything to do with stoves.
    Great find; where/how did you discover it?
    I consider the model 100 the true classic Primus stove as it is still being copied today!
    Regards, Michael Meijer

    Hi Tom, Check out this post of a slightly younger Primus 221L:

    https://classiccampstoves.com/posts/79789

    The box looks to be the same as the one used for your lovely Primus 100L stove.

    I also believe that your windshield is probably authentic, as you can see the same type came with my Pr.221L, and I have seen exactly the same form with Primus 96 "pocket" stoves.

    Best Regards,
    Kerophile.

    George your tin is wonderful . I wish mine was in such great shape. It does look exactly like the 100L tin - save the condition of course. Don't know much about the WS originality , but I hope it's OE to the kit.

    DutchMIke ,just getting over the sting of the price and you had to go and rub salt in the wound :roll: ](*,) Just kidding , I did pay a premium although for this kit - but I just couldn't resist, it's Stoveaholics Anonymous for me next :(
    Thanks for the info on the meths bottle - it appears it was never painted with any label ? Just plain , but engraved.

    Tom
