GEC 741
Many situations arise where either space is at a premium, or it is not convenient to have a telephone on a table. At times like these, the GEC741 is the solution. It can be mounted on wall, pillar or stanchion and protrudes only 11 cm (4 in). The handset rests at the top of the telephone where it is least likely to be knocked by passers by. The dial is at the exact angle for easy reading when the telephone is fixed at shoulder height. An off-hook position is provided so that the handset may be parked while the user is referring to documents, for example. The GEC741 has the same performance, and is based on the same tradition of reliability, as the companion table telephone - GEC746. The printed circuit, ringer, dial and handset are the same: the only differences are the slim-line case, the main internal frame and the cradle-switch linkage. The telephone is available in the popular colours of dual-grey, black, and ivory, and its smooth stylish exterior does not harbour dust. The plastic used for the case and handset is virtually impervious to scratching and staining. The dial has a clear plastic finger plate so that the numbers beneath it are always visible and the black figures are printed on an antique-silver background for greatest clarity : both features help to reduce dialling errors. All the operating arrangements offered for the GEC746 are available for the wall telephone - shared service, automatic, C.B. manual working, operator-recall, call back and transfer - also up to 4 buttons, with interlocking action, can be fitted to give the facilities of the GEC710 and GEC740 switching-telephone systems.

weight: 1.7 kg (3.5 lb) Taken from a GEC-AEI Telecommunications Ltd publication DLT28A 5mAFS1268 & DLT28C 2mF378 (1968 & 1974) GEC741 The GEC741 was produced in different variants which can be identified by the circuit diagram found within the telephone. This model was used on telephone coin boxes. It used Telephone-Unit D92732 which did not have the Resistors R3 & R4, the Thermistors or the Regulator fitted. The telephone was fitted with a 150ohm resistor (connected to Terminals 1 and 10) and a dial with an auxiliary springset. This telephone can be converted to work on the UK plug and socket system, but please beware that transmission may be degraded due to the removal of the Thermistor/Regulator components.
