Stanley Holloway's helmet?
Sorry to sound like Sir Doyle the Dense, but what, exactly, did the "PW" stand for on the white helmet that Stanley Holloway wore early on in the film?
From what I can tell, white helmets were generally worn by civilians acting in a civil defense capacity, but there doesn't seem to be a lot of information out there on the accoutrements they wore whilst performing their duties.
I assume the "W" stands for "Warden," but what the "P" could stand for is a complete mystery.
Can anyone help?
