Not certain origin, but it looks very much like a Hasag Lipsia, even in small details. That disproportionate, ugly glass is ofcourse hardly the correct one, but since it came with it, I'll keep it until I know what to use. The text is as seen in cyrillic, and would perhaps say 'Promet' (Prometheus? Suitable name for a lamp...) since the last letter is 'dead'. It also says No.2 after 'Promet', but strangely enough that's in our western, latin alphabet. The on- and off manoeuvre says 'Z' and 'A', which means a German speaking country to me! I asked at the Guild some years ago, but no one there knew, but Conny pointed out the similarity with the Hasag Lipsia to me, and I must say he raises a good point; it is most likeley that this has some connection to Hasag. Perhaps even made by them for the Russian market. Link to my old question at the Lamp Guild. You will also see Conny's Lipsia there. It uses a clever mechanism with a plunger that gives a portion of alcohol to the preheating cup at the same time as the on/off valve is manouvered.
