FA: WWII era book with details on military radios of the time

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3569135812
Covers details of SCR-536, SCR-300, AN/VRC-3, SCR-694 military
radios of the time, including a chart of coverage ranges.  Neat old book
to 'put it all in context' with what the soldiers were thinking about.

Thanks for looking
