Can't help you on the recording, but here's what the approach charts looked like.
If I remember correctly the last RR in Canada was in Williams Lake BC. It was decommissioned in 1980, I believe. When that chart was issued - 1971 - there were four or five in Eastern Canada, this one in what is now Kuujjuaq, Frobisher Bay (Iqaluit), Resolute Bay and Sept-Iles QC. The NW leg of the YZV range split runway 31 down the middle.
The reason the YWL range was so late in being decommissioned was because they had problems siting an ILS because of terrain. PWA used to go into YWL with the 737 using the range approach. Apparently it was quite a ride.
