Ebay purchase, lovely stove in excellent unfired condition. The flame ring is coated steel and the pan ring is also steel, which looks as if it has been plated with brass, I don't know if that is possible? I am unsure if the burner is original. I can see no reason why it would have been replaced when the stove has never been used and I believe that Gustav Barthel produced stoves under the Sirius brand, so it is quite possible that is why this burner is with this stove. Does anyone know when these stoves were produced? I have looked around various parts of the forum but can't seem to find any mention of when they were made.
