I have a set of unused 1960 pattern combats, not too sure on the sizing's, I am 5'11'' and wear size ''L'' and have a 32'' waist, and these fit nicely. Trousers are adjustable so would probably fit a up to a 36'' waist?

looking to swap for a knife (something like the Enzo Trapper style) or a Tweed shooting coat in size ''L''.
