Portable radio in cream bakelite cabinet. Manufactured by HMV (His Master's Voice) at their factory in the London suburb of Hayes, Middlesex. This model was released just before the London Olympic Games of 1948, to capitalise on the expected boost in radio sales this sporting event would generate. Such radios were often referred to as the 'second set'. In contrast to 'house' radios, that often had a large freestanding wooden cabinet and were kept in the living room, these smaller compact and portable radios could be moved around from room to room.
