Sierra changed the nomenclature from Combat Vehicle crewman to Armored Vehicle Crewman on this helmet...the cut is also different than the standard CVC helmet...

I hate to use the word experimental but it is unpainted...a factory test helmet?

Few more pics…any thoughts? The earphones are held in place by a screw on the outside of the helmet, similar to APH-6 flight helmets

I found this link.

 

See the attached screenshots, the whole text is at the link.

 

Definitely is a "test" helmet, going off of the P/N. Dated 1973.

It's a prototype dated circa 1972. According to the sound attenuation and bump protection reports, it didn't do very well in testing. The photos from Natick show it looking just like that, without paint.

Here's a link to the bump test report.

 Thank you for the update and info....

 

again the forum members come through

 

the report did a good job of breaking down the test results...

Ok, so who got it on ebay?

[phantomfixer]

I dunno but he knew it was a test helmet, was informed the helmet was listed in a book by Chris Arnold....
