By RCA Victor Company Ltd. (Radio Corporation of America). A rare MI-22201 loudspeaker made for use by the RAF Intelligence and 'Y'-stations in conjunction with the AR88 radio receiver. Manufactured with a crackle finish black painted steel case, approximately 29 x 15 x 26.5cm sitting on four rubber feet. There is an 18cm/7" diameter 'RAF' grille cover with 'fretworked' stylised lettering typical of the 1930s/40s. The reverse reveals a 20cm/8" RCA branded speaker, associated wiring and socket. These speakers and the AR88 were used extensively by the Allies during WW2, notably by the Y-Service who were responsible for interception and analysis of enemy communications and 'Direction Finding' to discover the location of enemy transmitters. The RAF was also issued with sets, their speakers having the distinctive grille cover in place of the usual 'slatted' type. The case has minor surface corrosion, a small knock to the rear of the top surface (see photo) and the internal components are a bit grubby, otherwise very good. A really good looking piece that would grace any collection. Untested. Heavy. Stock code M27202.
