This is my first post here, so have mercy if I get something wrong. To cut to the chase though, I am a gas mask collector of some repute and I was traded a British Hypo Helmet by another collector. It was recommended to me that I come here to ask it's legitimacy. It's not that I don't trust the guy that gave it to me, it's simply my experience with WW1 fabrics is slim to none and I've heard tales of reproductions being passed off as the real thing. Thus, I appear before you.
I tried to get the stitching and material to show fairly well, I had to resize the images to upload them so I don't know how well that worked. I'll get more photos if anyone asks.
