early Zenith Royal 760 (1959) has a genuine cowhide case. The radio
is so early that it used components manufactured for use in tube radios
(e.g., a massive chassis as opposed to lighter printed circuits, big transformers
rather than the miniature transformers used in later radios.) As a result,
the radio is built like a battleship, weighing in at almost five pounds!
Note that the grille looks like an automobile grille. This was a trend of the mid to late 50s.
This radio is sensitive, tuning medium wave (MW, or AM broadcast) and long wave (LW), which is below the broadcast band. LW has little, if any, program material. I hear LW beacons for direction finding and atmospheric phenomena.
