The problem is this... The college in question was called "South Mersey College" (qualification awarded in the 1960s), which was, in 1986, then (with 7 other colleges) merged into 4 colleges, the college in question being (I think) the "Riversdale College of Technology". Then in 1991 these 4 merged into the "City of Liverpool Community College". I've contacted them, and they don't know!! I was hoping that someone might know of some secret government record archive, but seriously doubt any such thing exists!!
