I bought this canteen cup from China and its an aluminum cup. The original cup handle was very short, I removed them and replaced with a longer rod made from an old hanger, mold them according to the curve of the cup and I have a homemade US GI Canteen Cup.
About the stove stand, I made it from thick steel wire, bought from hardware shop. The reason why I shape them like this is that it can be placed togather with the canteen cup and the bottle into the original pack. So, I have got a full set of bottle + Canteen Cup + Stove Stand with a modified pack.
Will show you guys about the canteen cup next time. This posting is more about how I use the stand to cook/boil water.
