GEC Telephone No. 707 or 711 Prototypes

These pictures are from the GEC Telephone Works at Coventry.  They were taken by the GEC marketing department and show different stages of development of the GPO Telephone No. 711, which GEC also sold as the TEL/2W.

GEC won the design for the 700 type wall telephone, which on paper was called the Telephone No. 707 but was officially released as the Telephone No. 711.
