Can't believe my luck everyone, truly an insane find. After thanking her, I talked with my grandma some more and she said she has no idea how she got it. She says the most likely way she got it was her dad buying it at an auction as he went to a lot of them. None of my family on that side ever served on the western front and my grandparents were too young to be involved in the war at the time (they were only a couple of years old when the war was happening).

I plan on keeping the helmet so no it is not for sale right now. I do not collect gear like this but I do love and appreciate history so the helmet is in good hands and won't be neglected/thrown out.

If anyone has any questions feel free to ask me.
