I owned one of these , A50 Cambridge, from 1982 until 1997 when I gave it, and an A40 Somerset, to my son. He uses the A50 as a backup to his daily driver, an A40 Farina. It was built in October 1954 and registered on January 1st 1955, making it probably the oldest A50 existing. It has lift up door windows and no cut out in the bootlid for the fuel filler cap.
