There were 2 privately owned H&R T48 rifles registered to the same address in Alberta.
I'm told that the regimental collections were largely "cleaned out" shortly after the FLQ crisis - most of the "good stuff" was destroyed to remove temptation from potentially rebellious QC'ers.
There were a decent number of Ex1 trials rifles manufactured as, or traded for T48 and X8E1 type rifles. This is probably why while the US trialed the folding trigger guard, the UKtrialed the charger loading top cover, but Canada
adopted them.
