Fabulous photo, john70, not the top of Bradford Street but the bottom - just passing Mill Lane.
The interest to me is that the Alltyres building behind is the former Buckingham's coachbuilders, who did a few bodies for Birmingham Corporation until foundering in 1930/1.
I am one of a group researching a plane crash in this vicinity in march 1944 when a Wellington bomber, HD987, suffered engine failure and crashed between Bradford street and Digbeth either on or just behind these premises.
As there is a date of 1923 on the building (just above the bus destination panel) then this part at least survived - this is the first picture I have found of Buckingham's works. Thank you so much!
Below is a picture of one of Buckingham's 1922 products for BCT, a small Leyland 'A1' 20 seat saloon that was one of the first one-man-operated buses to run in the city. As can be seen, they didn't go far to take the photograph, the Markets were just opposite the works!
