The Royal 300 featured a large chrome face with a porthole window for the tuning dial. The earliest 300’s had the words “Seven Transistors” printed at the top of the faceplate, but Zenith soon changed it to read “All Transistor”. The lettering on the back was well protected when the radio was laid down by two little “feet” at the top and a third foot rest on the bottom of the battery door. I don’t know why Zenith didn’t continue this as it seemed to work fine, but the 300 is the only model that they did this to.

Zenith produced the Royal 300 in four colors. You can commonly find them in pine forest green, and black. The maroon ones are more scarce and the white 300’s are very rare. In fact, I have seen only three examples; mine which is pictured below, a badly damaged one listed on ebay in early 2006, and the fine example in Norman Smith’s collection.

The unique styling of the Royal 300 makes them a highly sought after collectable, especially when found with the metal face still in nice condition.
