    At last a genuine original No.5 silent tube burner complete with the original inner and outer burner caps. What a relief not to have to fabricate special replacement caps for once!
    This stove would appear to date from just a very little later than this other, externally identical, example. The key difference is hidden from view inside the pump tube, it is the pump rod. The pump rod is the early Svea version of the modern standard assembly, i.e. without the fixed back-stop behind the cup carrier. Identifiably an early Svea example of this rod assembly because it still has the both the Nybergs Patent cap and the signature Svea pump carrier and end nut both with all round components and no hex flats to aid servicing!

    First firing after full service and many years of disuse:

    And barely 10 minutes later:

    Remarkably quiet in action, but still boiled a full Simplex kettle from cold in what seemed next to no time at all:thumbup:

    Nice find.

    Hi Ian, what a wonderful early stove, nicely presented.

    I am also interested in the spirit cup, and wonder whether it originally had a “shroud plate” self igniter:

    https://classiccampstoves.com/threads/early-optimus-burner.7184/#post-68287

    Your photo of the spirit cap and its dimple also shows a brass rivet on the bridge in the spirit cup. It seems possible/likely that this might have attached the shroud plate at one time.

    What do you think?

    Best Regards,
    George.

    @kerophile, yes George, the spirit cup would originally have had a vertical flame leader held by that single rivet, but which is now long-since lost. There is a good photo of a nicely cleaned up original Svea silent tube-burner spirit cup in this other gallery post. The complete assembly illustrated there shows clearly that the form of the flame leader used on these tube burners was different to those used on later ('normal') Svea silent burners. Notice how the leader top had a flattened dome shape with a central notch cut out, quite unlike the later spear pointed design.

    Two gallery entries which show different Svea models but sharing the same dating features as this one can be found here and here.
