Zenith Radio by Harold N. Cones Ph.D., John H. Bryant, Martin Blankinship, William Wade (1997, Paperback, Illustrated)

I am a long-time radio collector who is interested in the history of radios, especially the best known brand in America. Zenith Radio has plenty of documentation and pictures about the early years of Zenith. Whether you are a collector or dealer, this book will help you spot those old Zeniths. The price guide is marginally helpful, but price guides rarely are good. I highly recommend this book and you should consider adding the books for later years.
