    This is an example of the very first, 1895, incarnation of what became known by 1898 as an Ultraprimus No.1 soldering iron furnace apparatus. The stove at the centre of the apparatus has a hexagon fitting screw-in pump the same as in this normal stove example of the same date. But since it was not being sold as a free-standing stove in its own right it is not fitted with legs and has absolutely no markings on it at all except for the old-style B.A.Hjorth provenance mark on the tank base. The burner fitted was of the type that was also used on the contemporary Hjorth Vesuvius blow lamps, which also first appeared in 1895. These specialist pieces of apparatus would have been marked with the 'duelling blowlamps' soldering equipment logo had they been made in 1896 or later, just as ordinary Primus stoves were marked with the stylised stove logo from the same date onwards.

    The special cradle and soldering iron heating frame and box are also slightly different from those shown advertised only a couple of years later:

    The relevant page in the 1898 B.A.Hjorth catalogue clearly shows the two key changes which had already been made to the specifications during those first 3 years of production:

    Notice that by 1898 the screw-in pressure pump had been replaced by a fixed pump following on from the adoption of the new patented NRV design. And notice that by 1898 a sizeable chimney had also been added to the iron heating box in place of the tiny vent hole which was all that had been provided in the top of the first version of the box photographed above.

    Where in the world did you find that treasure?! :thumbup::thumbup::thumbup:

    That is a great piece of stove history.

    So, what's your technique like with surface-mount components? Maybe you use one iron for 60-40 and keep the other one for modern lead-free... :)

    @Mark Avis to be honest I don't separate irons between traditional & lead-free. It is easy enough to simply wipe the irons before use and choose whichever of the dozen or so at hand is the most appropriate type and weight for the task in hand. That said I only normally use lead-free on items to be used for food and drink, and then the clean/wipe is done quite thoroughly:D. The great advantages of this wonderful Primus furnace is that the irons are held much more stably than on a blowlamp clip, it can cope with heavier irons, and it facilitates rotating pairs of irons rather than having interruptions in work waiting for reheating:content:

    I'm sorry, I was making a silly joke about the kind of minuscule electronic components one has to deal with in modern equipment for repair (another hobby of mine, but I'm a bit of a simpleton there). Dealing with such with an electronic temperature-controlled iron and an illuminated magnifier (sometimes even a binocular 'scope) is really tricky. It would be...entertaining...to try it with your setup :)

    Ah, so! I had no idea what you meant by "surface-mount components":doh: Way over my head; must be living in the wrong century:lol:

    Excellent @gieorgijewski , a real piece of clear, incontrovertible documentary proof that, as suspected, these special soldering furnace assemblies did date from at least as early as 1895. Where on earth did you find that!
    Many thanks,
    Ian:thumbup:

    Beautiful piece of history and still as usable today as the day it was made. Thanks for sharing.

    Not so many currently made products are not usable after 120 years... Hardly they last year or two. ](*,)

    Really handy for repairs to small stove pump tube leaks. Sorry lost the thread the problem was in. The large copper bits give sufficient thermal mass for quite big jobs, and possibly quite a bit more controlable
    than a gas flame.

    This celebratory advert from July 1894 shows that this earliest version of the Ultraprimus was already on sale as early as that:

    This is the earliest available image of the original (no chimney) version of the Ultraprimus, dating from 12th Dec. 1893, and celebrating its recent successful launch alongside the Vesuvius blowlamp at the 1893 Chicago World Trade exhibition (the Chicago exhibition had run from May-October 1893):

    Thank you Ian. There are *many historical details emerging in the last couple days. Stovies compare such details with stoves in-hand. Aside from the Hjorth name being positioned early and often !, ...for stove dating purposes, it's not clear to me when (pre1894) the Hjorth name 1st appeared on actual (Lindqvist & Svenson) Primus items.

    To add some closely related details 1892-94, as "The Primus" launched, and it sure did.
    > 1892 March, when 30 year old Lindqvist and Svenson formed J.V. Svensons Fotogenköksfabrik and first began their production of "The Primus" stove for sale to the public.
    > 189x they ^^^ soon formed a sole sales agreement with 30 year old Bernie (Berndt August Hjorth of B.A, Hjorth & Co.). Bernie "... had great vision and saw the chance to introduce the stove onto the world market." He sure did.
    > 1893 May the opening of "Chicago trade exhibition" (aka The World's Fair, Chicago / Columbian Exposition), where Bernie launched The Primus and apparatus (for the world to see).
    > 1894 by July 100,000 of "The Primus" stoves were already sold (link),
    along with, other apparatus.
    Bernie's "...worldwide sales contributed to rapid growth for both companies. The 2 companies merged soon after.

    *Ian, There's much credit to you for ongoing research and recent appropriate placements. It's also a credit to membership's collaborative efforts :thumbup::thumbup:. Ross had vision, provided a platform and initial research :thumbup::thumbup: (on his shoulders...), Staffan, gieorgijewski , Christer, kerophile and others continue to add/confirm historical details.. Bravo!
