    I'd enjoy that Kerry, will do.
    My plan would be to see some of Tassie whilst on bicycle tour.
    Unlikely I'd be hauling the 535 but I'm sure I could rustle up a cuppa on either my Trangia or my hotter camping stove, a Primus Omnilite Ti, which one, yet to be decided.
    Of course if theres a watering house nearby, a pint of dark might better ease the saddle sores.

    I'll check for numbers when I next unpack the box (for afore mentioned photo).

    I didn't see any numbers stamped where I think you refer to when I inspected the stove on its last exposure for inspection.
    In fairness the light was fading and my eyesight has deteriorated as I've aged and in my late 40's I'm likely overdue for glasses.
    I'm going to assume "any" stamp should be visible upon inverting the stove and not actually dismantling it which I'm not currently of a mind to do in the immediate term.
    Damage to the finish due to any clumsiness on my part is something I've a mind to avoid.

    I'll ask everyone ignores my spelling mistakes as this new for me Macbook takes it upon itself to alter words occasionally without notice, unlike my previous Windows machine

    Hi Rif,
    I am guilty of not being able to readily provide good zoom-in photos myself, like MANY members for a variety of reasons, so no worries there and not a show-stopper.

    To be clear I offered above that "our fellow stovies" (not me, yet) know your year production range. Re the 535 model, i will get one eventually and I am eager to learn something new. Here, I am more of a student than you are (vs the teacher) just sayin'.

    My impression from Kerophile's comment is the possibility some front panles may be without addl lettering.

    In-general, checking for maker's marks and lettering you want bright light and magnifier (although your NOS "should be" easy to see).
    Below are two examples. When you can peek at your front plate is it an exact match to the No.2 below? or not?

    1. "Note that the name is with raised letters and the company is still AB B.A.Hjorth & Co."

    2. VS "...the name is with recessed letters that have been painted white. The company name is now AB Bahco."

    Source of above info 2008 post by Guzz and full credit to him for that excellent post.

    Rif, If your front plate is slightly different, i am +1 with Kerophile in hopes we might eventually see more images. For fellow stovies images of NOS examples (esp of popular models) are great to see and important future reference as well.
    thx omc
    PS re the wire used to secure caps that is an in-general topic that can be covered other ways, my curiousity remains and i do welcome yourself or anyone to chime in but if not here / now that's fine too.

    This is what you're looking for on the spacer bar...

    G'day OMC,
    a quick squiz at the front of the stove and its "pump plate" shows wording to the left of the pump knob "AB Bahco." and to the right "Made in Sweden" so I'm thinking its the same as your photo 2 (by Guzz)

    There is no apparent writing on the tank unlike some pics in other threads.

    Thanks for the photos

    Oh and the wire appears to either be copper or copper plated, showing the same orangey tinge to it as the burners which being a different colour to the priming "dish", which in itself matches the brassy yellow of the tank.

    Does anyone know the model number of the silent burners?

    G'day Funfundfunzig,
    Thank you for the photo.
    Unlike the apparent zinc coated spacer bar shown in your pic, mine is nickel or chrome.
    Despite looking with the aid of a torch, I can make out "No" numbers sorry.

    Hi,with the AB Bahco marking your stove likely dates from the period 1955 to 1962:

    I think it probably comes from the early 1960s as there were two earlier forms of the Pr.535 stove, with the previous type of regulator control knobs. I believe this stove is from the second form of the cooker:

    https://classiccampstoves.com/threads/primus-535-cooker.4464/#post-332831.

    Note the earlier type of regulator knob.

    Best Regards,

    Kerophile.

    Thank you Kerophile for the approximation, much appreciated.
    Makes me appreciate its condition even more.

    Any ideas on the model of its burners and/or their apparent copper colouring?

    Hi @Rif,
    The 1955/6 Primus catalogue shows the Pr.535 with burner #4190.
    The outer cap, of Primus Metal, #4205 was fitted as standard, but the brass outer cap, #4197 was available as an optional alternative.
    The regulator knob/valve spindle was also available in two forms, #4121 or #4163
    (both knobs are as in my example of the No. 535 stove)

    The 1961 Primus/Condrup brochure, posted by John (Presscall) shows the newer form of control knob, such as is fitted to your Pr. No.535, in the stove illustration.

    The 1971 Primus Catalogue, posted by Trevor, has the No.535 stove fitted with burner #4195 and outer caps # 4676, although brass outer caps #4197 were available as an alternative.
    The stove illustrated has the newer form of control knob, such as are fitted to your stove.

    However, in the best tradition of Catalogues, the exploded diagram of spare parts shows "cookie cutter" control knobs!

    As to the question of the composition of the wire used to secure the caps in position on the burners, these were made of steel, possibly brass-plated, to stop them rusting in transit or storage. Brass and copper wire are no use for this application as they melt in operation. I have done the experiment!

    Best Regards,
    Kerophile.
