Swedish Military Trangia
Just a quick look at various stoves and cookers - mess tins currently available online and in your army surplus store.
The swedish - German army mess tins are not expensive, they are compact and tough, although a little heavy.
Fuel needed to run this cooker is either alcohol or Methelated spirits. You can conserve fuel if it is shielded well from the wind and this will help cook faster and with little effort.
