Offered here is a nice early leather portable from 1957 – the Zenith Royal 700. It measures 6.5″ wide and 4″ tall. It operates on 6 C batteries and when tested played to my satisfaction*.
The interesting thing about this example is that the leather cover is black, when all advertising media never mention there being a black option (this is only the 3rd example of a Royal 700 in black that I have ever heard of). All others are a light tan in color. The leather of this radio has survived in great condition. All original. If interested and would like to see more pictures, let me know.
*In order to play to my satisfaction, a radio needs to pull AM stations across the dial. The radio also needs to play with strong volume and clear tone and be a pleasure to listen to. The high standards I use to rate a radio’s performance assures that it will please you too.
