WWII RAF CARBON TYPE DESK MICROPHONE TYPE 3

Desk Microphone 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 was used with the 1154 Transmitter when operating as a ground station. See Item A0164. Its designation by the RAF is Type 3. It is stamped on the base 10A/9597 and on the microphone No22PX/1.

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.
