Magneto Telephones

This instrument is the equivalent of the modern Bakelite table set but arranged for wall mounting, and is ideal for indoor use where space is limited.

The casework is of the same neat design as that used for the automatic and C.B. sets and embodies the same new features, i.e. the case is gate-hinged and the cradle construction enables the micro-telephone to be suspended vertically over the front of the instrument.

The interior components, consisting of  "alnico" generator, anti-side-tone induction coil, condenser, ringer, switch and terminals, are mounted as a unit which can be readily removed from the case; alternatively, the case with equipment unit attached can be lifted off the hinges for maintenance purposes.

Sets are available with standard generators or, for long line working, with heavy duty generators.

When this instrument was supplied for either the Canadian or US markets it was fitted with a US type F-1 transmitter instead of the Transmitters, Inset No. 13.  In later models the Transmitter used was the US type G-1 (WE 500 series telephone) transmitter. The picture above shows the F-1 transmitter.
