    I scored these two lamps, a friend picked them for me and shipped to my address. Never seen something similar but after looking for info here I found nothing, these are for gasoline (petrol) per Neil’s PLC



    I may need a few parts to get them running back to life and I will post in the wtb section later.

    991 was found separately and 220J was gifted to me.

    Why gasoline?
    The straight vaporiser may also indicate spiritus/alcohol.
    Gasoline lanterns have a double valve on the vaporiser base.

    According to the paper 106u from 1929 the 820 is for "Gasolin" (light naphta / petroleum ether), the 820B is for gasoline / petrol / benzene, whereas the 822 is for kerosene / paraffin.
    That same paper indicates that the 887 is for "Gasolin" (light naphta / petroleum ether), the 887B is for gasoline / petrol / benzene, whereas the 886 is for kerosene / paraffin.

    I stand corrected ;-)
    Sorry my mistake.
    Would be interested to know what E&G had thought of to prevent a fire. Because you can't shut off the lamp when the foot valve (rubber) fails. If there is a foot valve.

    I think that at that time most of the pump valves were made of cork, and thus were more resistant against fuel than rubber.
    However, in the later years they introduced the positive shutoff valves for the fuel, at least for those appliances that were intended to be operated with highly flammable fuels (e. g. at the 825).

    No, I tore down the 887b and has straight pick up tube. I may convert them to kerosene, to risky to run on petrol (white gas).
    Neil’s PCL said for gasoline

    Good idea, although you might have to change the type no.s then :lol:.
    The only differences between those types might be the jet/nipple orifice and needle diameter, and today you will not get those for other fuels than kerosene. Except the Swiss 821/523, which are intended for gasoline and therefore have a slightly larger orifice.

    @Martin K. I have a bunch of kerosene vaporizers (around 20) that bought from eBay in a lot. All I will need are the needles and save the factory ones aside.
