    Hi,
    I'd like to present this nice Optimus I acquired several month ago. It was patinated and very dirty, so I had to clean it just to make stamps readable. All parts including trivet were original.

    I'am not quite sure about the year of manufacturing - seems to me 1920 - 1924.

    The stamp on the bottom of the tank:

    Pump knob, vent screw and filler cap ( same stamp on both sides )

    Original steel trivet:

    Exceptionally ( I never do such things ) I found for this stove cast iron trivet. Imo looks much better.

    With original trivet or adopted works great.

    Thanks for watching.
    Take care

    Very nice @Stanisław Grajewski, lovely details on these older Optimuses (Optimi's? ;)) with the filler cap shape and single, diagonal knurling.

    ahh another 1S "ORIGINAL" congrats!
    an interesting pc of history. thank you for detailed pics making this an excellent reference :thumbup::thumbup:.

    to confirm/learn on-topic members would want to double check what i offer as quick recap and IIRC:
    these ORIGINALS were made at some point during 1923-32 by OPTIMUS but at a Danzig factory.
    fwiw your trivet on this one: not offered in 1921 catalog, not shown in 1924 brochure, for catalogs on CCS it first appears in 1932, an "indicator" that narrows yours to 1925-32

    @Stanisław Grajewski An excellent example Stanislaw superb lettering especially the logo on the filler cap, the older the stoves the nicer and well made they are

    I hope you keep the steel trivet. I really like that type, far better than the ubiquitous pressed steel sort. Very forgiving in use in various ways, but relatively difficult to source.

    Unfortunately, I don't throw anything away... My replacemet had only esthetic reason.
