Hello, I recently picked up this original ESB37 aluminum canteen cup and whats interesting is the olive green paint. I doesn't look to be post war and has period patina. I know they didn't start painting canteen cups and mess tins in the olive green color till 1941 so, would this have been a "reissue" to conform to the new specs perhaps? or even maybe a old cup that wasn't issued till 41' from old stocks?
I'd like some more opinions.
