The Royal 300 is another example of the early coat pocket sized transistor radios offered by Zenith. Its chassis is very similar to the Royal 500 and the performance is also equal. Style wise, they are much different though. This 300 has a large metal face with a porthole window to view the station selector. This reminds me of the 1957 Thunderbird porthole window. Wonder if Zenith got that idea from Ford, or if it was the other way around? Size: 3 ½” wide, 5 ¾” tall, and 1 ½” deep.
The 7AT41 chassis is all original and clean inside. This unit does play strong and clear. The maroon cabinet shines brightly and is scratch free.
