GEC No's 340, 341, 344,
The instruments listed below and those described on the conversion telephone page are similar in both design and construction but differ in that the former are not prepared for conversion for use on other than magneto systems. They employ the same principal component parts, ensuring the high standard of efficiency which characterises all GECoPHONE instruments.
Alternative types are available for use on series and bridging circuits respectively. Five-magnet generators can be supplied if specially ordered.
Table sets are provided with flexible cords of suitable length for connecting together the pedestal, generator box and terminal strip. Wall sets include a standard metal mounting bracket for the pedestal but no cord for the generator since the two units, when installed, may he connected by permanent wiring.
* Dimensions do not include wall bracket.
