Spy Wireless sets were Manufactured in WW2. Click here for an interesting article about these Radios.
In this article it is suggested that they were manufactured by the Radio Communication Department of the SOE at Stonebridge Park. However it is believed that Marconi may also have been involved in the Manufacture of these Radios.
If any MVA members have any knowledge of Marconi manufacturing these radios please could you email Alan Hartley-Smith at
