Just a question and I wanted your thoughts. How common are m-1938 US tanker helmets? There is not a lot of information on the helmet on the web compared to other types or styles of US, German......etc helmets. Do people just not collect them? I just bought 2 in the last week I did not have one and needed one for the collection, I bought the second to keep the first one from being lonely. I will post both when the second one gets here. I pulled photos off the internet of the two I bought, both are Rawlings size 7 and 71/8.
