How many nations used the german helmet? Could you do a post on the helmets, so us amateurs can be armed with info so we dont buy something that isnt what it seems?

I sure can. As far as calling yourself an “amateur” I think every person who is into history is an amateur. I and every person who is into history doesn’t know every single little detail about WWII or any other era, so don’t think in those terms. I think Bill Nye said it best:“Listen to everyone..listen to everyone and learn from everyone, because nobody knows everything and every one knows something.”
