    Very nice. And its working too. Do you really use gasoline on that?

    @MYN That "B" would indicate gasoline along with the straight vaporizer. I would not use gasoline regardless of what the label indicates, too risky. My Px 2827B (1944) is suppose to be for gasoline but I won't chance it. Want to keep my eyebrows!

    I don't know why they also developed a gasoline version. Perhaps for military reasons. They wanted the same fuel as for planes, tanks, cars and many other devices. Except for the generator, this Petromax 828 B is constructed in exactly the same way as a Petromax 828 kerosene. It has no security standards. A few years earlier, Petromax had built real gasoline lamps. Modell 825.

    The 825 would be the real answer for gasoline in Petromax-styled lanterns.
    But I guess, with all the additional features, its a little too costly, both to manufacture and for practical military purposes.

    Still the 825 was missing a positive shutoff for the pump valve. It had one only for the fuel below the generator.
    And it didn't have an encapsulated pump valve like the e.g. Colemans or some of the Standard lanterns.

    Did the military not use more kersosene and diesel ?.

    As for costs for the 825: an extra shut off valve and pump airtube would do.
    but if someone has patented these features you can't use it. The 825 is in the 1930petromax catalogue.
    I guess that kerosene was easier to obtain for a lot of users than gasoline in those days.

    Ah...well I see. It'll still require the positive shut off for the pump. I don't know if it has the pump air inlet tube 'snorkel' so as to prevent direct fuel leaks like a Coleman.
    Petrol/Gasoline did not quite attain the popularity as in the USA.
    Perhaps, it was way more expensive than kerosene in Europe and most of the rest of the World except North America.

    The Petromax 825 has an extra valve.
    I am not aware if it also has a airtube like Coleman has. I think not. Because you aslo need another pump valve setup.

    The petromax style needs the fuel pressure to seal off. The Coleman snorkel idea needs a positive valve. Hence the airpressure will not seal.

    @WimVe, @MYN
    The Wehrmacht and the Luftwaffe preferred gasoline. Gasoline can be produced artificially from the liquefaction of lignite, but diesel cannot. In the Wehrmacht only the trucks ran on diesel. After the loss of the oil fields in Ploesti Romania in 1944,artifical gasoline became extremely important.

    Thanks for the clarification, WimVe and Reinhard.
    I don't think the guys in Luftwaffe would have wanted a lantern on board:D.

    It only has an extra valve to shut off the generator, which allows to extinguish it without releasing the pressure (very recommended at gasoline devices).
    The pump setup is the same as in all other Petromaxes: no positive shutoff and no airtube inside the tank.

    Correct, there is also no air release on the tank cap.
