@Marlen Dehmel I am intrigued by what you have told us so far. Thanks for the picture. Please tell us more, if you can and if it is not too much trouble. And please, do not worry about your English. If you use some German, I am sure another member here can help those of us who cannot translate it ourselves. @In The Dark Congratulations on getting the stove to work. Nice job.
@In The Dark The weak point of most DESCA (and many more) stoves after ww2 is the painting. There was no real heath proof paint finish at that time. After some use the paint is peeling off and rust will eat the stove. Only some more expensive alcohol stoves had the almost ever lasting enamel coating. Your stove was certainly made before the war. Does it have a (ceramic) enamel coating? Here the wooden knob is mentioned (second last picture): Unknown make of spirit stove This helps dating: Desca Alcohol Cooker Regards Radler
The first DESCA stoves has an enamel alloy. So the painting was very durable. The factory G. H. Wünsche, witch produced the stove also produced enamel pots and -dishes.
