There’s a fantastic website of more photos here.

HOV 928 at Cotteridge, 1956. Numbered 45, the sign on the front says, "West Heath Alvechurch Road", although it is facing the into city direction - it was Birmingham City Transport practice to show the outer terminus destination all the time. A chap downstairs in having a nap in the sunshine!
There’s also some great 80s photos of buses on Flickr – see these links:
