WARNING!!!!! STOVE GEEK RESPONSE
Another vote for the Optimus 111 T ot 111C. The 111T's can be picked up as surplus ( The Marines used them as did the US Antarctica service) and parts are still available from A&H.
These burn: Gas/ White Gas/Kerosene/Deisel with no change to the set up. With a new jet and a restricter ( 2 minute conversion time) they also burn alcohol. They are used in Antarctica by most of the countries that go there and are considered exceedingly reliable.
They weigh 3 pounds and are clad in a steel armour case. Construction is brass and steel with the only plastic being on the control handle. The most common problem is the pump leather dries out and needs lubrication, or the rubber washer on the fill lid dries out and allows a slow leak robbing the tank of pressure.
If you learn to dissassemble the stove and replace the shut off cleaning needle properly and fix non return valve when it sticks every 20 years... you might have a stove that can live for ever!
Here are three of the 111B's two of which I rebuilt. The B's burn white gas only the 111 burns Kerosene only and both have the roarer burner.
The two burner version of the 111B the 22 B. This stove is a cooking powerhouse and 7 pounds of beautiful engineering. 20,000BTU of wonderful heat.
Here is the 111T on a trip down the Mackenzie this summer. It has the multifuel capability and the silent burner as does the 111C. The silent burner boils water about 20% slower than the B's but can burn almost anything. The silent burner can also underburn if you start it while the priming flame is still burning. Let the priming complete itself and then turn on and light and you won't have a problem. The T's sometimes come with a o-ring pump rather than a proper leather cup. I switch them as leather is better below -20.
To tell you how much I love these old stoves I presently have, two 111T;s a 111C three 111B's and a 22B. No longer made so I figured I needed to secure a life time supply!
