I saw this helmet pop up on eBay a few days ago. The cover looks like it is original to the helmet and I can see where it looks like, in addition to drawing the 327th club on the sides, somebody traced a partial outline of the camo pattern.
The only thing that stands out to me is the fact that I haven't ever seen or been able to find photos of the 327th in Vietnam with similar markings on their helmets. Additionally, the reflective pieces attached to the rear of the helmet strike me as a post-VN thing. Any thoughts and opinions on the helmet are welcome.
