This helmet has been in the family for a long time as it was my grandfather's. Interestingly, it was the prize for winning a writing contest in grade school! This is not my collecting direction however I would greatly appreciate any info from the members versed in this kind of headwear. Maker, I assume from the name, is Juncker and the date is 1916. I could find no other identifying makes other than a '57' on the side. My mom claims there was a chin strap which was attached at some point but unfortunately, rotted. Would appreciate any information you can impart. It's staying in the family as it has been a great conversation piece. Cheers.
