Both the Vietnam and Korean War's M1 helmets were virtually identical. There are some differences between the World War II M1 helmets and the Vietnam and Korean wars' M1 helmets. The M1 helmets from the World War II era had a steel stripe that was rolled around the outer edges of the helmet.he M1 helmets during the Vietnam and Korean War eras had what was called a steel pot as the shell and they were a little taller. Most of them had some kind of helmet cover on them.

So, when a replacement came in, he got the old guys helmet.
