    When I saw this stove at the flea market, I had a hard time telling what it actually was. I'd never seen a stove this dirty before. None of the inscriptions were legible.
    But some signs pointed on a early Primus and after a careful cleaning of vent screw I could read PRIMUS.
    I did the rest of the cleaning process at home, which caused a brief conflict with my wife after the procedure was completed.

    Filler, pump and raising tube were resoldered in the past. Unusual cast iron trivet
    seems unoriginal to me.

    On the side wall of the tank there is an inscription in Cyrillic about the manufacturer

    The bottom of the tank

    On the bottom of the tank there is something what looks like the letter "P" turned upside down

    The rest:

    The next photos shows the low position of the alcohol bowl on the rising tube and the flat legs

    And at the end - burner

    This stove should have been manufactured before 1911.
    To my surprise it works without replacing or repairing the NRV. Pump washer and filler cup gasket had to be replaced, of course. Imo the yellow color of the flame is due to a decalibrated nozzle.

    Thanks for watching

    Very nice acquisition of a pre-dated No.1

    I like what you have done with the cleaning.

    Well done.

    If you take a clear picture of the Cyrillic text and put it into Grok and ask it to translate…this I have found to be a good method.

    Beautifully done Stanislaw- well cleaned to reveal the inscriptions, but without losing all the character of the 115+ year old veteran. You've captured the important features very well too in the photos.


    Oh dear :oops: Pleased to hear it was only brief, I'm sure you clean up any mess you make! :lol:

    What concerns trivet - yes, it was sold together with stove. Concerning Cyrillic text - not F. W. Lindqvist, rather A.B. Hjorth :)

    Thank, @Stanisław Grajewski

    AI obviously did its usual thing of conflating information and coming up with a slightly realistic but incorrect answer!

    ADDENDUM:

    When I used Google AI again using the label from the stove of @igh371 linked above, it gave the correct answer, so hopefully it’s learned something:

    @Stanisław Grajewski


    Could you please put photographs of the top and bottom of the trivet?


    Cheers

    @Stanisław Grajewski A very nice addition Stan, and a very good sympathetic fettle and clean, it now makes all the beautifully lettering and logos stand out yet not over cleaned and polished well done there
