This is a vintage 1950s UK Radio made by World Radio Limited London. When you turn the radio on, it says "Playmate" in the middle of the dial. Apparently World Radio Ltd had many models of these, such as radios that said Jaguar and Aston Martin in the center of the dial. This is similar to the Radiomobile radios of this vintage and is 12V positive ground. This is an AM only radio, made for the US market with dial numbers reading left to right. The radio is shown in an under dash mount but can easily be removed to mount into the dash of the car. The 2 front knobs are missing.
