- Registered as GHN 189 on the 10th August 1942, Fleet No. BDO29 changed to BGL 29 on Ist May 1951.
- The bus was sold to Silcox of Pembroke dock, South Wales in March 1959.
- It was withdrawn in November 1969 and bought by the Reverend Phillip Battersby in 1970 for preservation; later passing to this Society in 1981.
- In the mid 1980's considerable restoration work was undertaken to keep the vehicle roadworthy; it has recently had new rear springs fitted and oil seals renewed on the back axle. Further substantial bodywork and engine refurbishment will be needed for the next ten years of active life.
