Thanks. Funny, this is where I got most of my information originally when I was researching my helmet. I'm not a member there so only found it via a web search. Even over at US MILITARY Forum, you can see how little info is out there.
And thanks for sending Bugme a message. I look forward to hearing his feed back if he responds to you. I would be more than happy to speak to him if he wishes.
Really appreciate the help. I love this helmet and want to find out as much as I can. A real rare piece of history.
