I also scouted around for a "Trangia Mess Tin", but didn't end up buying one. Definitely too big for a pocket kit, but maybe OK for one inside your pack. As I mentioned above regarding the Nalgene bottle/cup thing, my quest was mostly to find something that I could use to carry collected water, and boil it.
