Greetings all. Here is a M1 I am considering but I am unfamiliar with this configuration of liner. Its nothing like I have seen in an M1 and it really doesnt match up with the age of the rest of the helmet. It looks like someone has drilled holes through the top to add this liner!
And again same with the chinstrap although it has US markings its unusual to me.
The shell itself I think is great...any ideas what the markings represent?
Many thanks in advance
