Admiral - Air Castle - Radolek - Sonora - 11" oval dial

 



               All these radios with 11" Oval dial made in 1936-1937 and sold under five brand names Aeronautic, Air Castle (Spiegel Inc.), Admiral (Continental Radio & Television Corp.), Knight, and Radolek. All radios shared the same large glass dial, wooden knobs, and grill cloth type. All companies built almost the same sets of chassis (AM3, AM4, M5, AM6, AM7, AM8), used almost the same cabinets, and service instruction looks exactly the same.
