Had this ages now...US Army PASGT (personal armour system ground troops) Airborne helmet.It is made by Unicor and is dated 1985.You can see the additional velcro tapes that join onto the chinstrap and the foam rubber crash pad at the nape.Both essential features on a parachutists helmet.The tapes stabilise the helmet on the drop and the crash pad protects the back of the head.
This was one of those random ebay finds.Badly listed, photographed and described!
