    I am not quite sure where to put this one as it is undated and un-numbered and is different to the 745 in the reference gallery.

    That's neat. I've no idea what I am looking at, but I like it.

    Quite a find.

    Take a look at the post of @igh371 HERE on early Primus apparatus, including the ‘duelling blowlamps’ logo.

    The French language catalogue extract Ian links to in that post HERE refers to the ‘Ultraprimus’ range of furnaces, but lists models with only up to four burners and not six. Other than that, it has some of the Ultraprimus model characteristics, but for the ‘joined’ spirit cups and heat shield disc and the fuel filler cap, which looks like a later replacement.

    According to Primus advertising some of the main intended uses of these stoves were in laboratories and for medical equipment sterilization. The key attribute cited being the ability to spread intense heat evenly over a wide area. See for example p.70 in this catalogue. In addition of course were the more obvious industrial applications.

    Is that a picture of it running on the lounge carpet?
    Reminds me of a line from a Procol Harum song. (and the ceiling blow away)

    That’s very nice! An early Primus rocket stove that’s still working.

    Are you going to clean up the dodgy solder?

    Cheers

    @Tony Press, he needs a bath first, then he can decide what to do with it. :lol:

    Yes , the work top was too close to the ceiling so the lounge floor had to do.
    @Tony Press
    I will eventually repair it. I was actually looking at the Aetna blowtorch to get the more appropriate time frame filler cap but it has the vertical finger grip attached which the other six burner stove in the “Other Models” does not have so it will stay as is for now.

    I am sure this is an early 745, 1910 or so.
    I have been browsing old catalogues and in one from 1913 it had the number stamped in the tank. The old logo with two torches also tells that as well as the marking of pump lid, FW Lindqvist.
    And made before dating stamping was launched. Primus made some design changes in the early years so it is not remarkable if details differs from later models.
    Only thing I find strange is that the three small feet are not there. Or maybe they have been remowed?

    Note to moderators - this stove/thread is in the wrong category section. The 'dueling blowlamps' soldering equipment logo alone places it 1896 or after and with other features much closer to c 1910 as Optipri suggests. Certain it should not be in this special section which is for the very earliest stoves.

    Fortuitous discovery of this page from a 1904 Baxendale catalogue solves the problem of the feet (or lack of them) - at the date that this stove was made, pre-1911, none of the 'Intensive' range of industrial burners yet had feet.

    Moved to "Other models" and title amended with the model according to Ian's sheet.
    If that is the correct furnace, it should be called "Intensive" No.6
    It can hardly be placed under the existing No.6 gallery since that is a totally different type.
    However! All that might just as well be the retailers own designations, so if it should be called No.745 after all is still a possibility.

    It is interesting to see that in the 1937 catalogue the page where these multi-burner industrial stoves are shown is still sub-headed as the "Intensive Series" even though it was then many many years since this group had all been renumbered with the adoption of the Primus common numbering system.

    Ah! Well spotted Ian.
    Some thirty years later, these large industrial lamps are called the "Intensive" series by Primus themselves (page attached below).
    So it's hardly a name just used by a retailer.

    Even the designation No.6 may be an actual designation by the manufacturer.
    The No.6 we generally think of is a larger one burner stove, but it wasn't present in catalogues at this early stage, so it's perfectly OK.
    The first time I can find a one-burner No.6 is in a 1913 years catalogue I got, and by that time the six-burner is transformed to No. 745 (with the later bun-feet, if I recall correctly).
    Just as in the 1937 year catalogue Ian mention:
