WWII RAF CARBON TYPE DESK MICROPHONE No 3

Desk Microphone No3 made from the Post Office pillar phone.
By WW2 the old Candlestick (Pillar Phone) was becoming obsolete being replaced by the 200 series Pyramid type, to help the War effort the British Post Office were able to find many of the old phones for conversion.
The Desk microphone No3 was used with the 1154 Transmitter when operating as a ground station Item A0164.

Your comments:

• This is made from a GPO Telephone No 2.(1920s) for "central battery" working. It had no provision for a dial and so became unusable for telephone use. The microphone is a standard GPO carbon transmitter No 13 or perhaps earlier No 10.
