Better pictures are needed, but from the looks of, i would say it is an American ww2 civil defense helmet.
Looking for militaria from 38. Batterie, Heeres Küsten Artillerie Regiment 977, also from 31, 32 and 36. Batterie.

very common and not very collectable, you cant even give them away, thats about how popular these are
especially for a plain white one without any insignia
yep,,,i agree with that assessment
As stated above, common, but worn and rusted,
even less of a collectible...........
They make nice hanging flowerpots...not being sarcastic, they really do!
Can't disagree with the verdicts already given.
I just took my own advice and googled "Zuckerman helmets" and what did I find.....lies.
The author clearly thinks that Civil Defence workers manned anti-aircraft guns during WW2.
Wrong. Royal Artillery (the Army) manned guns, searchlights, etc.
Civil Defence was not army and, in fact, a lot of Air Raid Precautions (ARP) etc. also wore military issue Mark II helmets.
The Zuckerman type was used largely by factory employees assigned to (e.g.) fire fighting in the workplace, and so could be classed as (wartime) industrial safety equipment rather than military.
Cheers again....sorry if I misled with my first post.
