pots nest together and stow inside the windshield. The set is completed by a small plastic fuel bottle. It is recommended that the fuel bottle and burner unit be stored separately, outside the pots (since alcohol may otherwise seep out). A Swedish army plastic mug can also be fitted inside the pots. The stove uses small sticks, wood chips, or pine cones as fuel. When using the alcohol burner, the Svea burner unit may advantageously be replaced with a Trangia replacement burner, which appears to be more efficient. Swiss The Swiss mess kit (French gamelle) was originally introduced in 1875 in the form of a pot made of tin-plated sheet steel with a lid and handle. That first design was however later deemed unsuitable and so in 1882 a revised design was introduced which is closer to the Canteen-cup system design: a tall, one liter canteen, with a stove (burns woodchips, etc.) that cups the bottom of the bottle and a cup/pot that goes over the canteen; the cup can fit inside the stove, better heating its contents. The 1882 design later formed the basis of the modern German mess kit design as mentioned above. British 1908 Pattern Mess Tin In the First World War, the British Army used a metal, two-piece, kidney shaped mess tin. The 1874-model was made of tinplated steel and had a "D" plan view with rounded corners. The tray or cup piece had a folding handle that opened to the side. The tray also functioned as a deep lid for the pan. This change from the 1854-model allowed the use of the narrow and tighter curved side of the cup rim for drinking. It also permitted the tray to briefly be held over a fire. The corners of the square shaped bail were also more rounded. The geometry of the older British mess tins was substantially different. The 1854-model was "D" shaped in plan view and was made of tinplated iron. It was fabricated from front and back panels of sheet metal. The tray or cup nested inside the pan. The handle of the tray or cup folded inside but was on the flat "back side" forcing the user to drink from the broadly curved front. The lid was intermediate in depth, could be used as a plate, and set down securely on the pan. The bail was square shaped and the corners were tight
