The RBZ was a portable miniature valve-based receiver, introduced in 1943 by the Emerson Radio and Phonograph Corporation in New York (USA) for the US Navy. The receiver was used during Naval raids – for example during the D-Day landings – but also by resistance groups for the reception of BBC broadcasts. In Naval use, the soldier's metal helmet would be used as the antenna. A short piece of fixed wire (approx. 70 cm) and a screw-on terminal is used to connect the receiver to the helmet. Although it is uncertain whether these radios were issued to US Marines during WWII, it has now been confirmed that British SAS troops used the RBZ Radio during Operation Houndsworth in Morvan (France) in June 1944. Marked ‘CVH-10204’ to the inside of one flap. Both receivers are present *untested*. The canvas and straps are in very good order. The price includes UK delivery. HE 851.
