    Hello fellow fettlers.

    I have just bought this Primus No: 501 (see pics).
    A new valve and new gaskets for the filling lid - which by the way is in an odd large size/diameter compared to all other stoves in this category and age - and she was running fine - incl. the adjusting mechanism.
    I have not been able to find any information on this Primus No:501 - can anyone help me regarding age etc?

    (In case this info is already on this great forum - I apologize) - Best regards and merry flames to you all.

    G'day @Harder D. Soerensen and welcome to CPL.
    I think this is a rare stove as there is no others listed in the reference gallery.
    There should be a date code stamped in the bottom of the stove. Have a look at his post https://classiccampstoves.com/threads/primus-dating-chart-1911-1963.11464/

    The stove is shown in this catalogue dated 1914 https://classiccampstoves.com/threads/1914-primus-catalogue-no-371.13644/ and this one dated 1917. https://classiccampstoves.com/threads/1917-primus-no-492.32573/#post-33260

    Thank you so much ROBB055.
    You are right about the stamp - it is an “A”
    (I get a “no permission to open your two catalogue links?)

    It's not the "S" ?

    Can be - but it is stamped “S”

    Could you elaborate on why?

    WELCOME Harder,
    What a fantastic 1st post! (candidate for gallery @shagratork ?)
    I am +1 w/ROBB and now you see that it is a 1911.
    Re size/capacity the "Oljebehallarens rymd 1.2L" has your 501 at the same size as 1911 No.s 1 & 5.
    I encourage you to subscribe to access the catalogs.
    That said I'll insert relevant pages (not sure I have permission to repost ref. images, if mods want to delete this that's fine too, seriously).

    for all I know it is a 1st on the site, I don't recall either a 501 or that original early regulated roarer R135 both are sweeeet ! well done
    thanks for posting, omc
    fyi for search R137 is early regulated silent

    @OMC - Thank you very much for the kind words!
    I have a small collection of old german alco-burners, Danish Ginge, Spanish Hippolito, one of the first Radius camping - and some primus/optimus ;-), so I am very happy to be included in this great forum!
    This 501 caught my eye, since I couldn’t recognize the regulator. The number 501 wasn’t mentioned in the ad.
    So I thought - for 17 $ with postage - I couldn’t go wrong
    :-)

    I have already moved it to the Gallery.
    But we might perhaps need a new category for the 501 models, which is a thing for Ross to create, so I have alerted him to decide.

    Thanks Harder!
    I think you have taken pretty many good pics of different details already, but we like to see all possible details in the reference gallery, so additional pictures are always welcome.:thumbup:

    Certainly have. Excellent close-ups of a rare stove. Brilliant, and welcome to CCS @Harder D. Soerensen

    Neat, features I think are real cool. Too bad the fiber? wheel is gone.

    @hikerduane and @presscall - Thank you. I don't think this has been used for a long time. The leather cup was very dry/hard, and when I unscrewed the rod, the leather literally just smouldered. The NLV couldn't hold pressure, so I changed it. Tried to fix the old valve but again the NLV-gaskets just changed to dry dust. I managed to fix a new gasket for the filling lid, but I need to find a gasket for the airscrew. Will try my local plumber. All these bits turning to dust - I think the same faith hit the fiber-wheel. It actually burns quite fine for a 106 year old stove.
    I also have a new Primus 111R - but this old stove is actually easier to regulate the flames on.
    I have yet to find one on the internet (Ebay, auction houses, yellow pages etc). The only place I found info was here on this great forum!

    all,
    My thanks again to Harder for this excellent example of a No. 501.
    To aid search I added R137 silent burner into text above. I should have added the 505 stove aye, :oops:.

    Credit goes to abbahco1's continuing his decades of contributions to the rare content found only on CCS :thumbup: . Without his posts I would not have (& could not have) made the connection to 505s in SRG. Both 505 examples happen to be 1914 btw.
    thx omc
