Here is one of my two Civil Defence helmets. It is the same as the helmet shown on page 16 of Tin Lids - Canadian Combat Helmets - 2nd edition by Roger Lucy. And as the book says, it would have been reissued in the post-WWII Cold War era to the city of Edmonton Civil Defence Corps. This one looks like it is in a bit better shape than the one shown in Tin Lids.
