- The chassis was built in I 949 by the Bristol Tramways & Carriage Co. Ltd. and was supplied to United with a standard Eastern Coach Works single-deck bus body.
- In 1960 it was converted to one-person-operation along with some 30 others. For this purpose, the driver and rear passenger doors were sealed up, and a new power door fitted at the front; the cab side screen was angled to allow a ticket machine to be fitted; and the bulkhead behind the driver's seat was cut away.
- The bus was sold by United in 1966 to J.T Bell (now Bellway Homes) for workmen's transport.
- Purchased by the Aycliffe and District Bus Preservation Society in 1983, restored between 1989 and 1996. It is the only surviving example of the 30 modified.
- The bus has starred in the Yorkshire TV series Heartbeat and Catherine Cookson's TV drama Round Tower.
