This is an early transistor radio from America. It's a "DELUXE" series radio, released around the mid-1950s as part of the "ROYAL 500" series. The size is approximately 145 x 85 x 35 (mm) and weighs 540g (including batteries). This radio's variable capacitor is an air variable capacitor, the same type used in vacuum tube radios, rather than a polyvaricon. It runs on four AA batteries. The transistors are cylindrical, not flat, which suggests it's from the mid-series. However, the exterior design is the same as the early models. The sensitivity is good; it can normally receive the main broadcasting stations covering the radio's location. There's a bit of static around the 650kc to 750kc range on the tuning dial, but it doesn't affect reception. The volume control is smooth. In terms of appearance, there are scratches on the speaker ring and body. There's also some peeling on the plated parts. Please understand that this radio shows signs of use from many years of age. It is intended for collection or display purposes as a vintage American radio, not for everyday use. The screw threads are slightly damaged, but removing two screws allows you to remove the back cover and see the internal layout.
