Original Austro-Hungarian M17 steel helmets, the classic coal-scuttle model! These were sold to Finland after the First World War and used around these parts for many decades, well past WWII. A very iconic piece of Finnish military history or military history in general. The second-grade stamp comes from the fact that one or both of the side-mounted "horns" are missing.
Not sold for any actual protective purposes, only as a collectible. So if you decide to crash your Harley wearing one of these, you can purely blame it on your own stupidity.
Condition
Very much used and the liner has been replaced by the Finnish army at some point at least once. The condition of the chin strap and the liner vary, but they are quite intact. The lining, rivets, and other fixings can vary a lot and be quite modern, too. Additionally, having had a looong service life, the shell might have small dents and scratches or rust stains. They have also been repainted with gray or greenish-gray, sometimes in multiple layers so the original stamps are hidden underneath. So, when you order one of these, it might not look exactly like the ones in the pictures. These are all very cool nevertheless!
The second-grade stamp comes from the fact that one or both of the horns are missing. They were originally used to attach an additional steel brow plate, Stirnpanzer. However, the plate was so heavy that it saw very limited use.
