I honestly haven't any idea where it is, but it must be within the old City of Birmingham boundaries, because it has a Corporation-pattern bus stop sign of the post-1947 pattern (with the sign projecting away from the road, as opposed to the earlier ones, with the sign symmetrically centred over the supporting post.
I'll guess it's along the Redditch Road beyond King's Norton, and south of Redhill Road, probably at the next junction with Longbridge Lane, right on the city boundary, which would explain the manky street lighting past the junction.
