Telecoms at Bletchley Park
The GPO's expertise from its research department at Dollis Hill was
invaluable in assisting Bletchley Park to develop robust,
electro-mechanical machines which could be used to break the wartime
codes.
Some parts for Tunny and Colossus machines were sourced from regular
telephone exchange equipment.
