This is a brass alcohol stove made by Sigg. It goes back a number of decades. It was probably part of one of their kits before I took it and made a pot holder from a pineapple can decades ago. Including the can it weighs 5 ounces and measures 4" across. The stove itself only weighs 3 oz. and I like using it in combination with rocks - I do not carry the rocks! Below: Fire!
