Brown side is also pretty rusted, and it’s stained throughout.

The pictures don’t do it justice, it’s nearly ripped in half and it super faded and soiled, there’s holes all over it to, I’ll try to get better pictures of the cover alone to prove it.

Honestly.... It looks in too good of shape to have been worn in country..Not by Infantry anyway.... The ones Ive seen that are deemed authentic are super faded,,, torn and oil spattered. dirty as well.

Ok, a little more context…   So as some of you may know, Native American families are pretty large when it comes to “relatives” I was just talking to him now and he said he found it in the house of his aunt but that house has just been passed down over 3 generations at least and rented by distant cousins of the family. He said that house is sort of a “family house” as there kinda on a small family compound where he found this one exactly. So the house has switched hands many times He said he doesn’t know who exactly it belonged to, and that he’ll ask them. He said it’s also hard to understand them, because most of them don’t speak very good English and either speak broken Spanish or alonguiquin which is there native language. So to be honest this is going to be VERY hard to figure out. I’ll keep working with him, and I’ll keep ya’ll posted.   hopefully this helped to some extent. In it’s own, what do you guys think of the helmet?

? Harjo   Wikipedia https://en.wikipedia.org › wiki › Harjo Harjo is a surname, derived from the Muscogee war title Hadcho or Hadjo, meaning "so brave as to seem crazy", "brave beyond discretion", "foolhardy", ...   Like 644td said... wouldnt your friend know who the relative is or was? And their service record? Meaning wouldnt they know if their relative was in Vietnam? And their relatives name? Right now as it stands... you have sort of an ID'd headband. You need more info to call it used in Vietnam.   Martys comment.... "Helmet and cover brought home from the guard unit more common. " I would agree. In fact, I think back in the day, when you mustered out of the Guard, you were allowed to keep your TA-50 gear which includes the helmet.  

Do you have any information on your friends relative. Salty doesn’t translate to in country it could be a NG cover. More information on the vet is key.  Covers brought home more common than a helmet and cover.  Helmet and cover brought home from the guard unit more common.  Do you have close up pictures of the markings on the back of the cover? Its alway exciting to find a marked cover   Marty

Both were repainted and named to Capt Roy D Metcalf O-277096. They originally were Medical Chests No.1 and the other unnumbered. Anyone care to research the Captain?

Wow neat collection. Thanks for posting.

To me there is no doubt this helmet was worn in country, it is way to salty to have not been.
