Sorry if I am posting this in the wrong area or something, this is my first post. I believe that this is a high altitude and cold weather mask for Air Corps pilots but have not been able to find any solid information on this item, or even if it is truly military. The only thing I could find on the forum was a slightly different mask from the 10th mountain so I thought maybe I would start a discussion on this item, assuming I am not mistaken, and it is military. It is worth noting that unlike most of the other cold weather masks I have seen this one does not have a snap for uncovering the mouth area. If anyone has more info it would be appreciated thanks!
