Very interesting and informative video.
I was in the first recruit course in the RCA Depot not issued Lee-Enfields and trained exclusively on the C1. We were the first squad to commence training in 1958. A few of the squads that preceded ours were retained in Shilo for a few weeks to convert to the C1. Considering that this was the Canadian Army, I'm not sure whether the emphasis was on marksmanship and fieldcraft or drill. Just kidding, I think.
On my basic para in Rivers we used some of the old FALs, probably on the principle that it didn't matter how hard they were used and thumped around.
