    Try www.fogas.se or The Base Camp (UK) for the lipstick burner, burner bell, flame plate and legs.

    Okay Tony thanks. Judging by swirl marks on tank I think steel wool was used to make shiny. Why do the feet look like a different material than tank and more prone to corrosion?

    @Punch

    Get a magnet and see if they are brass or steel. I expect they are brass but weren’t cleaned like the rest of the stove.

    It would be interesting if they were steel.

    Strong magnetic attraction to legs. I've never seen non-brass legs. Definitely not brass. Soldering looks to be factory quality.

    Mmm... Steel. I’ll have to check mine.

    Cheers

    My "Trois Etoilles", made by SVEA (N° 106) also has steel legs. I'll have to check the similar Optimus ones (N° 45/46) and my SVEA 106.
    I suspect steel (lower) legs were used on cheaper models.

    Best regards,

    Wim

    Edit; I checked my discus type stoves (sadly, no N°100) and found this;

    My Burmos (no engraving on the fount and no decal but it sports a Burmos marked burner) has brass lower legs as have my 2 Optimus N°45 models. Both the (SVEA made ) Trois Etoilles N°105 and the SVEA N°106 have steel lower legs.

    Hi @Punch Looking at the features on your Optimus No.100, I reckon that your stove could date from the 1930s based on the Bottom stamp:

    A B OPTIMUS
    O MADE IN SWEDEN O
    STOCKHOLM

    From the late 1930s they were likely using the Upplands Väsby factory marking, rather than Stockholm.

    Your No.100 has the filler nozzle with a flush fitting to the tank. From the early 1970s, until the end of production, the tank had a sunken section to accept the filler nozzle.

    It is not unusual for discus shaped stoves from this era to have steel feet.

    It would be good if @OMC would comment on the dating of your stove.

    Best Regards,
    Kerophile.

    Ok gentleman all fascinating as usual. Appreciate it. Never fail to be amazed at the dedication folks have to their various hobbies. Should I be in Fettling forum for questions?Ive been checking past posts. My goal is to get it running. No paper weights here! So I've contacted Base UK for availability of burners. Kerofile has talked about alternate set up so that it can be used in interim. So original burner was lipstick style which was dual purpose, silent and roarer? Im able to build up pressure in tank as well no damage to NRV after inspecting. So first step need burner preferably original.

    Hi, it can be difficult and expensive to obtain a lipsticks and all the
    other burner parts for a No.100 stove.

    In this thread you will see an economic method of fitting a multi-tube roarer or silent burner to a No.100 tank. The process is completly reversible so you can always fit a lipstick burner, if and when you find one:

    This post describes the options that Primus offered for their No.100 stove:

    Hello again (some had a sneak preview of this comment :lol: ),
    Thank you kerophile.
    As a compliment to your above observations :thumbup::
    *Mid 30s, or late 30s use of "UPPLANDS VASBY" began (use of "STOCKHOLM" ended). *credit a Bryan suggestion (we welcome details on-topic).
    So re the STOCKHOLM on the bottom... for Punch's example, it can get more complicated but for now, his "o STOCKHOLM o" tentatively places it mid 20s - mid 30s (an early/mid 20s example used "x STOCKHOLM x"), as I recall.

    re "Should I be in Fettling forum for questions?"
    You asked... you may have many questions, I do suggest create a new post (yes, like you did with your Meva? :thumbup: ), maybe stove forum.
    For repair or stove restoration start to finish, fettle forum... imo.
    That said, re what topics go where... history tells me, #2 carries a lot of weight:
    1. the site's categories are cleverly setup for you (read category descriptions on home page),
    2. enjoy it, "you do as you wish" or as you see fit,
    3. moderation is hands off approach, mostly.
    thx again omc

    With so much brass being used at the factories in the old days it just seems strange to use steel for legs. The learning continues.
