This helmet is One of a Kind. My grandfather chrome plated it at his factory in the 60's.Since then it has set around inside the house. I have seen these in movies/ news reels used by Navy gunners and Air Force gunners. This helmet does not require a liner. A leather/ canvas headband clips into the notches.
