Well, this seems the thread to assist my quest, over the years have often wondered.
Back in 1991/1992 as a fresher at (Edinburgh) University we had an older black gentleman on our course (in his forties/fifties) and once our paths crossed in the cafeteria/refectory and we had a coffee together - he opened up and told me that he was an ex 1-11 captain, for a Scottish carrier. Later on in life I often wondered whom this carrier was, perhaps at the time he told me but my memory fails me.
Were their any Scottish operators of the 1-11 in the 80's or has my memory failed me again?
