[Milsurplus] Recent Manuals Acquisition

[WA5CAB at cs.com]

Groups,

I recently acquired off of a list few of you are likely to be on a lot of 
TM's.  Most either I already had (some misc TM 11's) or are on some less than 
particularly interesting Navy receivers or test equipment.  But two were 
originals of TM 11-200 (SCR-AF-183 through SCR-AN-183 and SCR-AL-283 and SCR-AN-283) 
and TM 11-227 (Signal Communications Equipment Directory, Radio Communications 
Equipment).  I've been looking for both of these for years.  John Scott did 
copies of the latter many years ago and I have one but copy equipment back then 
left some of the photographs somewhat less than optimum.  I'll be doing 
reprints of both probably this winter.

However, and the main reason for the post, there was a civilian textbook in 
the stack that I almost told the seller not to send.  "Aircraft Radio And 
Electrical Equipment", H.K. Morgan, 1939, Second edition 1941.  Most of it is as I 
expected basic chapters on electricity and electronics as it might be applied 
to late pre-war aircraft radios and electrical systems.  But the chapters on 
Commercial Aircraft Receivers and Commercial Aircraft Transmitters instead of 
just having a token one or two example schematics have dozens.  At a guess 
probably the majority of what was in use in the commercial fleet at the time.  And 
in many cases, there's more than just a schematic.  As an example, there are 
six pages and a foldout devoted to the RCA AVT-7B, three for the Lear UT-6 and 
ten for the WECo/RCA W4A transmitters.  In the receiver chapter, besides 
communications receivers like the WECo W4A, RCA AVR-7, 7A and several other 
letters, Bendix RA-4C and RA-6, there are also a few radio compasses covered, such 
as the Bendix MN-12A,  about eight pages, Lear ARC-6, five pages and Sperry 
Mark I, three pages and a large foldout.  I doubt that there would be enough 
interest in the entire book to be worth the effort to reprint it.  But if anyone 
has a pre-war aircraft set they'd like a little information on and if it's in 
this book, I can copy the individual pages pretty cheaply.
