Just received this in the mail. It has provenance to about 1965 and I didn't realize it when I bought it (Kijiji if you can believe it) but it is named to a "Vatter." The really strange thing is that it has a dent from the inside that is roughly bullet sized..... I think a very cool helmet for less than $500 CAD! Sorry that the pics aren't better but the light isn't great today and my camera just ran out of batteries.
