    Hi. Today I managed to get ( for $15) this old stove. It has some modifications. Homemade slightly " mangled" pot supports , and an adapter for the burner. The screw-on burner is a roaring Premier, the origin of which I do not know.
    On the bottom of the tank is stamped code C so according to the table the stove produced in1913.
    I looked through the reference library and found only a parts catalog from 1925 (unless I missed something) in which the dedicated burner for this stove is a vaporization tube (lipstick) type burner along with a bell and plate.
    If I am wrong,please correct me.
    Ps. For now I do not try to restore it to work, but when I find time I will do it and report back.

    Great stove, well presented @Knee

    As you suggest, it would have had a ‘lipstick’ type burner, as mine (undated, pre-1911), and a cast iron trivet.

    Thank you very much @presscall . Beautiful flame on your 100.. Still a question. Can it work properly with such a combined burner? Will a standard 0.32 nozzle be suitable?
    Greetings

    Absolutely, yes. The original lipstick burner has a jet orifice of 0.23mm (same as a ‘96’ stove) but the tubular burner you have is more powerful with the 0.32mm jet. Some much later Primus 100 stoves came as standard with a tubular burner, but didn’t of that vintage.

    @Knee if you are going to continue with the existing burner you will need a flame spreader and some taller pot supports.

    It looks like the top of the burner is level with the current supports. If that is the case, when you place a pan of cold water on top of the stove it will suck all of the heat out of the top of the burner and you could end up with a very sooty flame or extinguishing it altogether. The vaporization process starts in the longer tubes and continued through the passages in the top of the burner. If you cool that disk down it will affect the quality of the combustion.

    There is approximately 13 - 14 mm between the top of the burner and the bottom of the pan on my Primus 210.

    Regards
    John

    Hi @Jeopardy Thank you very much for your advice.
    I am just in the process of straightening these supports. After straightening, I can see that the rod is quite long. I think that after forming to the desired shape I will get the distance you are talking about.
    Thank you very much for your advice.
    I will, of course, inform about the results.
    Greetings sincerely.
