WW2 German Luftschutz helmet

This is also known as the “Gladiator” helmet.
Helmet still has the original paint.

The decal on the front is partially missing.
On the inside there is a painted label from the producer with the size and price.

No liner and chinstrap.

****EDIT 21 March 2021****
Added 2 photo’s of the inside of the helmet.
This after some questions from persons and more close inspection of the helmet.
Just above the black text block in the helmet is a production number stamped in the metal.
Also I found the initials “H.M.” scratched in the inside of the shell.
