Mess tin verses Billy Can

[Timelord]

I was having a chat with someone the other day about creating an expedient bread oven. First I was on about digging a pit to act as an oven, then my co chatter and I thought, why not just cover a pot on the fire. This led to myself suggesting adapting 2 mess tins so they could be clamped together. Very clever me thinks :-) Then later I see this thread & I thinks to myself - DOH!!!! Billy can. Of course. Why was I even thinking of messing about with mess tins???

Basically I think the clue is in the name ---- MESS TIN ---- as in a tin for using in or at a mess... Not exactly a self contained cooking implement like the Billy Can. God, I'm so stupid sometimes.. lol.
