The school in the photograph is the senior school looked at from the playground of St Thomas's Infant and Junior School on Granville Street, Edgbaston/Lee Bank - (now Ladywood?) The senior school was, I think, called Lea Mason. I left St Thomas's School in 1959 for KE VI Camp Hill Boys' Grammar School in King's Heath, having passed the 11 Plus. The railings on top of the building prevented pupils falling from the rooftop playground but did not prevent the occasional beanbag being (accidentally) lobbed over during PE lessons! The former site of St Thomas's School is now the Tesco store on the corner of Granville Street. Can't imagine a third floor playground now.
