Converted to a one-man-operated vehicle in 1976, it was withdrawn from Portsmouth service in 1980. The bus then ran for a coach operator in Hemel Hempstead until 1987 when acquired for preservation. Although its then owner did a lot of work on the bus he was unable to complete the project and it was acquired by the present owners in 1994. Restoration work since then has involved relining the brakes, replacing the lower panel work, restoring the destination apertures to their original layout, renewing much of the interior wiring and upper deck flooring, replacing engine mountings, and finally undertaking a complete repaint inside and out.
