This is a lantern I was quite pleased to find. It is the first variation of the 1050 and has the original 1050 generator without a cleaning mechanism. This is the first time I have ever seen one fitted with an original generator. Anyway, the lantern is from 1932 and marked W 30. It has the torch for lighting screwed into a well in the tank that you fill with alcohol. An interesting feature is a sleeve around the burner tube just above where the generator enters. This can be raised revealing a slot. At first I thought this might be a way of tuning the air supply but I now think it is a way to get a pricker to the jet hole. I have never seen it mentioned in any catalogues so this is guessing.
