I just purchased this helmet. The seller claimed it was a German m36(?) made by Eisenhuttenwerk Thale. I knew it wasn't because of the ridge in the middle, but all of the Bulgarian helmets I've seen have had relatively small rivets on the sides, and these appear to be very large. Could there have been any truth to his story? or are they possibly post-war? Any info would be great.
I'll have more pics once it arrives
