Hi
both myself and a friend took a punt on these. These are the pics of mine.

His tin is green-painted with red squares on the bottom (from memory) corners. The tools and the metal-work of the scope on both were lightly coated with cosmolineicon. My bracket has AR 3453 and a JG stamped on it. The two caps are marked A43 and B44. The tool is stamped Tool No32 STG TEL Mk1.
As you say, the mount looks a fake. Not too sure about the tin or the tool.
However, both the scopes seem the real deal (are there fake Mk1s about?) Optics are bright and the windage and elevation work as they should.
