I picked up 2 Sutherland Rifle Sight Co. Ross rifle rear sights at an estate sale. The elderly gentleman said that the peep sight had been mounted on a Lee Enfield. Can anyone confirm or debunk this statement? Without a special mounting bracket, I can't see how the sight could have been mounted on a No.3 or 4. Of course, being a peep sight it would have to be close to the shooters eye.
