Panasonic RC-70 ball-shaped 1 alarm clock

This vintage Panasonic RC-70 AM/FM 1 alarm clock is in very good condition. There is no scratching to the glossy plastic or perspex surfaces, and the only sign of age is some yellowing to the white plastic casing (see pics below). With a diameter of 14cm (5.5 inches), the device is fitted with a UK-style three-pin plug and can be powered either from the mains or by a 9v battery (not supplied) housed inside a flap under the base. Both 1 and alarm clock are fully functioning, and the alarm can be set to buzz or just to switch on the 1.
