I know someone who worked with Bulmer in the 80's He's not sure whether it was Reel 1 or 2 of the Master of Nics first LP (1/4 inch) But, It was definitely propping up a table.
Quite where it is now, we'll probably never know.
PFR...I don't think that Leader stuff ever made it to cassette. It was very much a cottage industry, Don't think that the cash would have run to that....(Let alone Reel to Reel releases!)
Might be wrong, but, I've never seen a Leader cassette.
