    Hi fellow collectors,

    A few days ago I got this stove from Czech republic. It is very special because it has two separate spirit reservoirs for pre heating and for running the stove. The pump has two valves, one is connected to a tube that pressurizes the small reservoir separately. Once pressurized you have to open the red handle to fill the pre heating dish. The black handle on the left is the pump. I will take some photos once restored. The following photos are courtesy of the seller.

    As promised some photos of the restored stove:

    Fully assembled

    2017-08-26-19-42-55.jpg
    The parts after sanding, polishing and two fresh coats of satin black paint.

    The fount. The round bottoms are made of brass plated steel and had some rust spots, so I sanded them and used a metallic brass paint and a clear coat to protect them.

    2017-08-26-19-48-24.jpg
    The small chamber of the fount containing the methylated spirit for preheating. Have a look at the air tube for pressurizing the fuel.

    2017-08-26-19-50-04.jpg
    The larger chamber on the left side containing the methylated spirit sourcing the burner. Note the two pipes coming from the pump tube.

    Another point of view.

    Watch the two pump valves that unfortunately seem to be soldered in place.

    2017-08-26-19-53-53.jpg
    The burner unit.

    2017-08-26-19-54-13.jpg
    The burner cap on the right.

    2017-08-26-19-55-11.jpg
    The original instructions label, one nut with a cardboard washer for fixing the fount/label and the fixing screw for the preheating dish. Below are the new replacements. The label is etched from a piece of white copper (Neusilber) and was made by a etching technology business, I got three of them because of the standard size of the metal sheet used in production.

    2017-08-26-19-55-33.jpg
    Only the preheating dish missing.

    2017-08-26-19-56-30.jpg
    Photo from above, the small nickel plated brass nuts are used in modelmaking, regular DIN sized nuts were too big in outer diameter.

    Close up of the label:

    Pump first! about 20 strokes,
    then let out methylated spirit (red)
    until groove in the dish is well filled,
    then light methylated spirit,
    when almost burned - not too early -
    open mandrel in the middle (wheel).

    That is an absolutely beautiful restoration job. Having a new label professionally etched was well worth the effort and expense. It really sets the stove off and makes it look new rather than restored. I'm always amazed at the talent around here.

    Thank you all!

    The photos don't show everything. If you have a closer look you still see the corrosion pits although I used a satin black heavy-bodied paint. Especially the preheating dish has a lot of them.

    The paint I used is named Brantho Korrux 3 in 1, you don't need a primer, it is primer, rust protection and finish in one and absolutely not harmful. Since last year available in spray cans, it sticks even on flash rust or zinc plated surfaces and has approval to be used for kids toys or at the inside of food containers as well as on pipelines or oil platforms. It can be painted over itself at every time. Very good stuff.

    My intention was to conserve such an unusual and scarce stove for the decades to come but the label that was originally made from aluminium was badly corroded and could not be saved. So I scanned it and used Inkscape software to make a drawing for the etching process.

    In the end I am satisfied with the result, there is another stove already sitting in the shelves waiting for restoration :D
