Holy Grail : real M1 Vietnam combat helmet ?

[Military94]

wonderful THANKS to Battle gear and René, your job is just G.R.E.A.T !!! ( I would love to see the serial number on heavy helmet too soon now... )

Seems to be:
Line 1 reads as follow: HEAD BAND LINER HELMET.
Line 2 reads as follows: DSA-1-4813 (Which would be 1965).
Line 3 reads as follows: 6415-153-6671.
