I cam across this helmet and was wondering if anyone had ever seen on before or could confirm its authenticity? I have read that there were some cut-out style M40’s that were used to accommodate head phones and things of that nature, but I’ve never seen a WWI cut out helmet with the first pattern Luftwaffe emblem. The wear looks honest, but the Luftwaffe emblem really throws me off. Possibly a helmet used in the very early years of rearmification?

Any help or insight into this piece would be appreciated.
