At a camping only event, I have a medium sized iron pot, and a small, cast iron, domed lid pot that works as an 18th century Dutch Oven. Plus a copper pot and a small copper tea kettle. (The lid on the "Dutch Oven" when inverted and laid upon coals, also works for frying).
On the trail I have a small, brass, trade kettle, and a pair of soldier's mugs, called "cans" in some circles. Into one of the cans I punched two holes near the rim, and added a wire bale. So I can hang the brass kettle, and the bailed mug over the fire, and use the third mug for dinking. I could just carry the two cans, but I found that the brass trade kettle also works well as a container if I'm going to mix up some "twist bread" from my rations. I also carry a canteen, and have been known from time to time to carry a very small, steel skillet.
