I would view this with considerable suspicion. It is a Canadianissue W&S scope, although it is unfortunate that the picture doesn't blow up enough to clearly see the serial number marking on the scope. The case is Canadian. However, the "smudging" of the serial number on the stock is really suspicious. The III looks sloppily applied, and why is the crucial piece, which is the serial number itself, so faded out, and the letters LL are oddly spaced. I think someone has monkeyed with a military Mk III to "match" the serial number to the scope. The mount would be interesting to see but they don't show it.
