Viet Nam Navy Helmet w/ liner - eBay (item 110538359034 end time Jun-02-10 09:21:45 PDT)
Here is an Original US Navy helmet worn during the Viet Nam War. Both helmet and liner are in excellent condition.
I asked if there are any markings inside? and he said:
The inside of the helmet reads..."UMAL-10-63
or 68, and under that is printed "GD". And it is dark blue inside and out.
I told him it's a Belgian "Gendermarie" helmet and not a USN helmet but he doesnt believe me and insists it's a USN issue helmet
