    I'm expecting to receive an old Primus No. 1 without date code at the bottom. I'm not really familiar with Primus stoves so I need some help dating that stove.

    Due to the fact I didn't receive the stove yet I'm posting photos from the seller. Better photos will follow!

    Ciao, Bastian

    Pressure tactics from @presscall. There are very many folk who know a lot more than me. But for what its worth, and from what can be seen in the photos, your stove @Sternenlicht appears to be a rather nice example of a Primus No.1 dating from between 1898 and 1910. Especially nice in having such a good condition original cast iron trivet. The 'DRP' registration on the filler cap shows it was prepared for sale in Germany. The combination of the round B.A.Hjorth base stamp and the 'AKT.BOL' abbreviation on the filler cap place it no earlier than 1898, and obviously the lack of a date letter means I can't be later than 1910. A little bit more narrowing of the possible date window could be made depending on the pump tube cap inscription and the form of pump rod assembly, but these are not visible in the photos.
    The Juwel burner is not original, but a perfectly viable running replacement as can often be expected over the years. When you get the stove in your hands take photos of the pump rod and pump tube cap and let us see what they are like.

    Dear Ian @igh371, thank for your first evaluation!

    Great, that will be my oldest stove right now . As soon as I receive the stove I will post more and better photos with the named details.

    Thank you John @presscall for giving a notice to Ian.

    Ciao, Bastian

    @igh371 Your modesty does you credit Ian, but your collection of and experience in exploring/fettling ‘early stuff’ is exceptional.
    @Sternenlicht You’re most welcome! Congratulations Bastian on acquiring a beautiful classic!

    I received the stove! Here are some quick shots made with my mobile phone. I hope they are good enough and help dating the stove!
    The stove is in a great shape; no dents, no resoldered legs, the trivet is intact and only a little rusty.
    Only the burner is not from Primus, but also seems to be quite old.

    I will clean the surface with acetone only to solve the laquer similar hardened kerosene (or whatever that may be).

    Any help dating the stove is appreciated!

    Ciao, Bastian

    @Sternenlicht - very helpful shots of the pump assembly. That complicated looking lump on the end is the older form of assembly. The fixed brass backstop on the rod, fronted with an additional leather washer, provide the seal for the floating leather pump cup and carrier when they are pushed back on the pressure stroke. That form of pump rod assembly seems to have been superseded by the simpler 'modern' form by c.1908. So that narrows your potential production date range down to a window of ten years, with outside parameters 1898-1908.
    The pump rod end cap is commensurate with that dating window, but worth pointing out that it is the least frequently encountered variant of the pre-WW1 pump caps. Nice.
