Thanks David. The images from your descriptions bring me a large smile.
That's a good idea about checking with CBC... their markings are on the cassette!

Reel #4 is also now up.
https://youtu.be/dtDhnMqkBIY - the first time I watched any of reel 4 - it's great! The sound doesn't seem to be a problem, and the stories are not just informative, but fascinating.
