[ForSale-Swap] WTBl RADIOTRON DESIGNER'S HANDBOOK

[Rich Fowler]

I'm looking for the 4th Edition (red cover) Radiotron Designer's Handbook 1952.
  The condition doesn't have to be great. Maximum I want to spend on this is $25.
  My son has taken an interest in electronics, after me bugging him for 20 years,
  and has started building tube projects, like preamps, power supplies, etc. The
  old ARRL handbooks and internet are good sources, but nothing beats having
  one reference book that answers the questions. 
   
  Thanks In Advance,
  73,
