Well, it looks as if the "England" was stamped over the C/l\, so perhaps it was there before the rifle was exported as surplus. If the mark was applied over the "England", then it was struck after the rifle was surplused. Were SMLE rifles acquired by Canada, and marked during WWII? If that happened, the marking pattern could be different than on a rifle that was WWI Cdn. issue. When No. 4s were issued to replace the SMLEs in Cdn. overseas service, what happened to the SMLEs? If they remained in the UK, they could have been sold surplus along with UK stocks. Problem is that there are stamps around, and a Cdn. marked rifle might attract more interest.
