I recently found this one on ebay and am happy to have it added to my collection. I emailing the seller and found out that it was purchased at a estate sale of a vet and this was the only military item the family had other than his medals. I did some more research and found out the vet was a member of the Royal Canadian Armoured Corp. As to whether this was his helmet or if he traded for it at some point will never be know.
