Not sure if this is the correct place to post this thread but I just got this Vietnam era M1 helmet from a buddy of mine that served in Vietnam. This was NOT his helmet, but he said he picked it up sometime after the war. I’m pretty baffled with this one as the camo cover has "The few, the proud, the marines" written onto it. I figured this slogan was created after the war but perhaps I’m mistaken. The liner looks different to me as well, maybe airborne? There is an anchor stamped into one of the clasps, while the camo liner band is inscribed with the words "Go Army".

I’m assuming this helmet has been put together with various, mis-matched pieces as I’m assuming the camo cover, liner, and camo band did not all go together originally. Any information or advice on this would be much appreciated!
