Here is a near mint example of a beautiful maroon Zenith Royal 300 with its great porthole tuning window, just like some cars of the era. This 1957 radio measures 3 ½” wide, 5 ¾” tall, and 1 ½” deep. The radio is clean in and out and it plays as it should. This is what they must have sounded like when new. It operates on 4 AA batteries. Clean in and out, the seven transistor chassis is original and without repairs. The original leather case has taken on the wear and is in average condition.
