I picked one up a few years ago at a gun show. Nice condition. fair price, unfortunately a civilian version. Found a peep sight but haven't mounted it yet. My High School Cadet Corps had racks of them in the 60's. Never saw the bolts as we used them for drill purposes. I often wonder where they went. I do know that as CO of the local Army Cadet Corps I returned 5 very nice functional No's 7 back to our support base at 8 Wing Trenton to be turned in DP only rifles.
That was a few years ago. At least I knew their fate!
We used C7 in our high school. I never saw an 82. It would be interesting to know how different schools got different rifles. My high school in Ontario was a cadet school and used all Enfields for training. Same with the local sea cadets.
