|Magneto Table Telephone
In this instrument the Bakelite cradle stand surmounts a case work which is entirely of black enamelled steel relieved by gold bands and transfers.
The case is slightly larger than the one above and therefore, as it accommodates a larger generator, the instrument is eminently suitable where a very powerful telephone is required.
It is fitted with the most modern type of micro-telephone which incorporates a very highly efficient "inset" transmitter and receiver which are readily detachable. Generator 5-magnets, ringer 2000 ohms and a special feature is the anti-side-tone induction coil.
Overall dimensions 11 x 10 x 5.75 inches.
Weight 12.75 lb.
Note. Lightning arresters are not fitted in the terminal blocks of the above telephones.
