Reading the thread on canteen cup cooking, reminded me of the Billy cup, or "broiler" used for most every thing, has a cover.
I first ones I saw were being used by a couple of guys I met at Rendezvous.
They were Civil War re-enactment guys, so the period was a little later than I try to stick with, mountain man era, but I was impressed.
Thinking on adding one to my gear.
So far found a few, but this seems to be the best deal so far.
Here's a site, need to order by phone though:
