Hi all, This alcohol donut lamp has been stored in my "cold case" box for maybe twelve years. The tank was cracked and several burner parts were destroyed or missing. A couple of years ago I found a scrappy sibling and now I have tried to puzzle the parts together. It is a kind of puzzle as there are many parts and the burner case is very tight. I also had to make a new fuel feed tube as the original had a crack. Finally got all the pieces together and got it to shed light again, maybe after 110 years of its birth. This is a Hugo Schneider HASAG alcohol donut "Lipsia" lamp for domestic use indoors. Could be find in a 1910 Hasag catalogue ( Jürgen Bredenstein hytta.de) and also in the 1911 Goldberg catalogue. A very sophistic alcohol fed lamp with an integrated automatic pump filling a pre heater cup. Ca. 100 CP according to catalogue info and a nice looking small donut lamp. I have searched Hugo Schneider Hasag patents for this lamp, but struck no luck! /Conny ......and the "before" image ….
