I'm not in the office now but this sounds like something similar to what I've run into occasionally with some Sony V1K one-inch videotape for type C machines from that same era. I'll look into this as I have some of that stock on hand. The solution to squealing and general struggle in the transport was to bake for a shorter period with sub normal temperatures. Your mileage may vary in your situation though.
