I have been reading this thread with interest as I own M85 serial number 00232F. It's a real tack driver and one of the most accurate rifles I own. I would like to change the scope as I have the same S&B as Gil's, but the mount on my M85 the rings are too small. I am not optimistic about getting a correct mount. Also, the green metal transit case is on my wish list if anyone has one? I have attached a few pictures. The target picture was the last time I used it at Bisley, I can't remember the distance I think it was 300 Century.
