Here is one you may not see every day, not a camp stove, but still interesting. Note the concentrated flame type burner, which is unfortunately missing it's spirit cup. Currently not a runner, and the restoration was mostly carried out by the former owner, who lacquered it, something which I am not fond of. Still more fettling to do as there are some lacquer drips and scratches, and I would love to see it run again. My apologies for the poor photos due to low light conditions and no tripod.
