The Collector's Guide to Antique Radios: Identification and Values (7th Edition) by John Slusser, Staff of Radio Daze. Publisher: Collector Books, May 2007.  I have the 5th edition published in 2001, which is the best identification guide I have found. Not details, but lists just about every tube radio made in America from 1920 through 1972. Great photographs, good descriptions, and sorted by model number. Perfect for easy identification and with the model number sort, makes it easy to determine the year made as some radio designs did not change from one year to the next. The values shown are not realistic. Although, I have not reviewed the   the newer edition (7th) first hand, I am confident it is a good investment, and the prices may be more inline with todays market. Ruby Lane Staff Member.
