Swedish.
My Austrian Phoebus 625 is of the same design but larger and of steel.

Mountaineering stoves.
I can't say that my Phoebus has kept me alive, but it's kept us damn comfortable at times, using it as a heater.

Paid $11.00 for that Phoebus at the 1975 REI Spring Sale in Seattle. It was advertised as "used" on a REI-sponsored expedition.
