At some point in the early 1950’s, my grandfather moved to Birmingham where he trained to become a telephone engineer with the General Post Office (later British Telecom), presumably putting to use the skills he learned as a Telegrapher in the Navy during WWII. Does anyone know where he'd have done his training? Was there a GPO technical school in the area? My gran worked at the Botanical Gardens and they lodged at Francis Road on the boundary of Ladywood and Edgbaston, near Five Ways. Thanks.
