    Just in time for our CCS gathering at Newark, nudging aside my usual Tilley gassie is a sophisticated, beautifully designed and engineered - but above all highly practical - twin-burner butane stove.

    The Selzam Camping-box

    Top detaches. Top and windshield flaps are steel, rest of the stove frame and the gas bottle are in aluminium

    Founded in 1946 by Paul Selzam, the company is still in business Selzam website (French and German)

    Something of the company history, translated from the website


    Here's Paul and his wife Margrit with the Camping-box

    Marketing the product, appropriately in an outdoor location

    It's a large stove, though thanks to the (mostly) aluminium construction it's not too heavy. Size comparison with another stove having a built-in windshield and outboard-mounted fuel tank, a Primus 51

    Instructions and various warning notices on the windshield flaps

    The straps that hold the fuel tank when stowed usefully stow away themselves when the stove's in use

    Undoing one set screw enables the lot to be removed from the frame

    Control knobs held on control spindles by a flat on each spindle and screws - access holes to remove/instal fixing screws by lining up with holes in mounting plate

    Jets are Campinggaz pattern - almost. Threads aren't quite a match

    Fuel/air tube pushes (a loose fit) on the jet barrel

    1432506695-21.JPG


    Burner dismantled. Corrugated washers

    1432506703-22.JPG


    No O-rings in sight. Seal is by a rubber disc/diaphragm

    1432506714-23.JPG


    The conical tip of the sprung-loaded valve operates on that seat in the valve housing

    1432506724-24.JPG


    Spring installed

    1432506735-25.JPG


    Diaphragm, control valve tip and spring and brass disc 'tappet' that prevents the turning control spindle screw from abrading the diaphragm

    1432506749-26.JPG


    Assembled. A gas-tight seal is assured by the diaphragm

    1432506761-27.JPG


    I'd to replace the existing diaphragms. I coated them with silicon grease to see if they'd loosen up and become flexible

    1432506773-28.JPG


    They didn't and I replaced them with nitrile discs, cut to suit. I'll sound out Ross for some viton equivalents and they'll be that bit more durable.


    A measure of the quality is this example of a pot rest. Solid aluminium, streamlined form

    1432506802-30.JPG

    1432506816-31.JPG


    Fuel tank is a masterclass in aluminium welding

    1432506829-32.JPG


    Connecting up to the stove, the tank mounted on the stove frame by engaging lugs on the tank in slots in the frame. Chunky brass connector wing nuts are left-hand-threaded

    1432506844-33.JPG

    1432506860-34.JPG


    Control valve on the tank, with another wing-nut fitting as a secondary safety measure to prevent leakage in transit or storage

    1432506879-35.JPG


    Full range of flame control from simmer to a useful maximum

    1432506900-36.JPG

    1432506918-37.JPG

    1432506935-38.JPG

    1432506958-39.JPG


    Bit of a breeze blowing and I used additional windshielding

    1432506979-40.JPG


    Handy that the fittings are Campingaz control valve compatible. Refuelling is easy

    I think you're right, AR, the handwritten text on the fuel tank probably is a name, most likely identifying the dealer or perhaps the customer when an empty bottle was exchanged for a full one. It's been written in a felt-tipped marker pen and after initially wondering whether such pens had been invented back then have established they were in common use by the early Sixties, so it's possible.

    I've translated the data on the windshield flaps and some key points are:-
    Use windshield flaps if it's windy [stating the obvious!]
    Centre a pan on a burner
    Protect gas bottle against direct sunlight
    Don't connect up the gas bottle near a flame
    Before connecting up the gas bottle, check seals in connecting pipe are in good condition and replace them if necessary
    Extinguish flame on ending a cooking session by closing the gas tap on the gas bottle first, then the gas taps on the stove
    Gas tap on gas bottle must always be at the top when stove is in use [a warning intended to prevent feeding liquefied gas to the burners no doubt]
    Bottle exchange. Shut the bottle tap, screw on the closure tap and carefully pack the bottle in a cardboard box to post to your dealer or directly to Selzam Esso Gas, Winterthur. Handle the bottle with care, damage will be charged to the customer. A full bottle will only be provided on an exchange basis. When full, bottle contains 3.8 kg of butane gas and this weight and the total weight is indicated on each bottle. Weigh bottle when it has been refilled, particularly if it has been refilled by a dealer who only occasionally provides the service. The total weight must never exceed the figure indicated on the bottle. Danger! [not a lot of faith in the calibre of some dealers!]
    If one or both burner flames aren't as intense as usual the jet(s) may need cleaning. Used compressed air and never a needle.

    Hello presscall

    Here ist the translation of the text on the tank base:
    PRFDR. 10 AT = Prüfdruck 10 atm = test pressure 10 kg/cm²
    GEPR. EMPA = geprüft EMPA = tested by EMPA (EMPA = Eidgenössische Material Prüfungs Anstalt (the former official Swiss Federal Institute for technical tests)), the date of test 14.4.1961 and the number of test certificate.
    9.80 = September 1980, date of the periodical test after 20 years. Steel tanks for compressed gases had to be tested more frequent (i.e.7 years).

    The "M" with the little cross in it is the stamp of the EMPA. It is always besides the test date.

    The handwritten "Stuchi" seems to be the family name of the owner, but written wrong: "Stucki" would be correct.

    The other text is easy to understand: the weight empty 1.7 kg, weight of the gas 3.8 kg and the total weight. This text was mandatory on all gas tanks.

    This tanks of Selzam are very solid and light. I once found one (full) without the stove and used it several years for a brazing apparatus. Unfortunately they are made for butane only, not for the today more common propane, so I never dared to fill it again.

    Many thanks for the information, Radler. I'm very grateful.

    I'd worked out the 'weights' information on one mounting lug of the tank but couldn't decipher the rest. Fascinating stuff indeed!

    The stove was a real asset at Newark and I have it on holiday in Kent with us right now. Photos and captions on its travels when we get back.

    I saw the stove working at Newark.
    In fact John cooked meatballs for both of us - delicious!

    The stove works amazingly well.
    When I first saw it I could not get over the huge size of the fuel tank.

    @Radler
    Radler kindly sent me a link to an auction site which although expired still had these photos retrievable.

    It's frustrating not to be able to see the interior, but what's visible doesn't resemble the Selzam Camping-box innards.

    I'm inclined to think it's a very well crafted amateur production rather than a prototype, or early production model of the Camping-Box.

    Paul Selzam's vision was surely for an aluminium-framed and boxed stove and the distinctive fuel cylinder as a complete package.

    To have constructed the fuel cylinder and compromised on his original concept by pairing it up with a painted wooden box seems inconsistent with his innovative approach to design.

    The box, folding windscreens and legs seem to have followed a contemporary Coleman dual-burner design, such as the 6J.

    Thanks again Radler for a fascinating discovery.

    John

    Looking more closely at one of those photos of the early days, I believe I could be wrong. Those early Camping Boxes resemble the example Radler located.

    That stove is almost (only almost) enough to make me interested in some gassies!

    Cheers

    Late to the party.
    Wow, that's a cool stove. Almost makes me want a gassie. But, if we all did that, John wouldn't have all these gassies to take such fine photographs of. :)
