Looks like a Mk2, with the fifty yard increments on the range drum. I am only speaking from memory but the markings look generally similar to the other few Italianscopes that I have seen. I'm not sure if they reworked British
& Canadian
scopes or made them from scratch themselves. The bracket looks real enough. It's a Rose Brothers example. The Dutch also made some beautiful No32 (Mk3 scopes) just after the war......
