For those of us that enjoy the search for the "perfect" PSK tin, this might fit the bill...
WWII British Soap Dish [img]

Perhaps someone here has already found this, but I wanted to share. It's a an old British Army soap dish. All aluminum and appears to be uncoated so could be used to heat a (tiny) amount of food/water. Almost the exact H x W as the Altoids tin, but a little deeper at 1.5 inches. And it has nice rounded corners and lid so it should feel good in a pocket.
That little bit of extra room might be just enough to put that one more piece of gear or two in the kit without being too bulky to carry...
Hope this helps,
