Depending on the whether the helmet is an actual WWII helmet or assembled after WWII. Could be as low as $40.00 + or as high as $100.00 +. You would have to do research on the helmet, to determine what Mk the helmet is (Mk III = WWII, Mk IV = post WWII) The differences will be the placement of the rivets and the liner.
Yours has a WWII liner, making me think it's a Mk III.
The II on the liner might be due to the fact that the Mk III used the same liner as the Mk II Brodie helmet. In fact must troops when they got the new helmet, took the liner from their old one since it was sized and shaped to their heads.
Check the helmet shell itself for any markings/stampings that could help in narrowing down the date maybe.
Thank you, I have done research just not great at it, apparently it was used on d-day, issued to one British regiment, however I can't be sure. I cannot see any markings on the shell as its been re-painted a few times which also confirms usage. Where else might I look for markings or is cleaning it a good idea?
