||I am trying to trace a friend called Derek Salmon who came from Islington in London and ran IT Operations at City of London Polytechnic then London Metropolitan University when its status changed. He had a place in Hoddesdon Hertfordshire as well as a flat in Islington. When I last worked with him in the seventies and eighties he had a long term girlfriend called Lyn a secretary to MPs in Westminster. Lyn was Scottish and it's possible he may live in Scotland now . If you know of Derek I would, with his permission,like to contact him as would our mutual friend John Armstrong. Many thanks in advance.
