NATIONAL TELEPHONE COMPANY
Pattern No. B42 & B45
Both comprise - Granular Carbon Transmitter mounted in Nickel-plated
B44 (illustrated to the right) is fitted with a Double Pole Spoon Receiver,
These two very neat complete Telephone sets, calling- in connection with which is done by means or a battery, are similar except that the one is fitted for and with a Spoon Receiver and the other for, and with a Double Pole Receiver.
The former is a slightly lighter receiver than the latter,
but both are equally effective for the purpose for which they are required.
