To me it looks like a row of US cans with a loose Brit can at the end , and a row of Brit cans with a loose US one . And by the way the US did have 2 styles of cap on their cans . IRC , the round , screw off cap was on water cans , and the flip top was on fuel cans , that way you can't f*ck up and fill the fuel tanks with water during a blackout lol .
