That single deck bus JOJ 245 (2245) has been preserved Roy by a Group based in Acocks Green. Entering service in 1950 and withdrawn in 1969. They were Leyland PS2 with the higher powered engines also in BCT's other Leynad buses and their bodies, of a very high standard, were built by Weyman, Addlestone, Surrey. Similar bus 2255 is also preserved and one of these, for sure was used, for a private school (or institution) in Torquay for a few years after BCT sold it to the scrap dealers, who were usually W. Bird & Sons of Stratford-upon-Avon. I often saw it in my travels and I believe it was the one in the photo.
The reason the 30 buses of this type (JOJ 231 - JOJ 260) were bought by BCT in 1950 was due to the low railway bridges in Bournville and Northfield encountered on route 27.
An interesting fact is that in their early years, on the quieter week-ends, some were hired to Midland Red who. it appears, were short of coaches on the shorter holiday excursions to Blackpool and Weston-Super-Mare. So they got around a bit!
