My wife bought an old helmet from a car boot sale a few years ago. It seems to be a classic British helmet world war 2 era shape. However it is black with a white V on the front. Any ideas who would have worn it? ( I thought of an Air Raid Warden but I thought they had a W on their helmet) tried to attach a picture but appear to be a bit too much of a IT biff to do it here so have posted in Photo gallery.
