When did it come from Pebble Mill in Birmingham? I made a lot of studio items for Folkweave(when Peter Pilbeam was producer and Tony Capstick the presenter) and it was always in the Manchester studios then.That would be late 70's, early 80's I would guess. I have a few tapes from that era that Peter P passed me, but I imagine most got wiped unless people had a particular reason to sneak them out.
