Historic Flight Numbers BOAC
I am trying to find out the flight number of a BOAC flight from Croydon to Durban (routing was, I think, via Malta, Cairo, Khartoum, Nairobi, possibly Blantyre, Salisbury as was, Johannesburg). The year was 1948 and I believe the aircraft to have been an Avro York.
Any help much appreciated - if not the answer, then suggestions on where to look.
