I'll second ESH's opinion on the military's polyethelene cans. They are awesome, I only have one, they aren't cheap, getting hard to find, and I wish I had more.
I think they are made by a Canadian company called "Scepter". These things are heavy duty, quiet, and if you get the right scew on spout, pour fast, and don't leak a drop!(don't know about how they woek with the old style screw on nozzles-but they should fit)
I found my can under a crashed airplane(somewhere where I shouldn't have been), but Specter, I mean $pecter Offroad carries them. I bought my pour spout there for $17.00 or so. The cans were listed at over $50.00...
Your right I was looking at these Thy are nice at the local surplus are like $24.00 to $28.00 used for gas & water I would replace the NATO can with em, when I need to.......Dusty
