[GreenKeys] Fwd: Re: Which manual(s) to service a TT-4A ?

[WA5CAB at cs.com]

The basic number for all (USA) manual numbers applicable to this family of 
teleprinters is TM 11-5815-206-  USAF uses a different system which they 
change about every 3 to 8 years ever since the end of WW-II.  I don't record 
them..


I also have no idea as to why the -35 manual was replaced in later years by 
a -34.  They did the same thing with the -35P (Parts Manual)

There are PDF's of  TM 11-5820-206-12, TM TM 11-5815-206-20P, 
11-5815-206-34 and TM 11-5815-34P-1 online.  The first two have one thing in common.  All 
photos are black blobs and totally unusable.  The Parts manuals are 
illustrated with drawings of assemblies and although most of it is meaningless 
today, because of the drawings may be useful.  

Without going into the details of what all of the numbers mean, I have an 
extra original of TM 11-5915-206-35 and -35P from 1959 and 1963.  The -35P 
would be useful if you had a box full of brown envelopes full of Kleinschmidt 
parts with no identifiers on them except for the FSN or NSN.  Otherwise, 
probably not.  The early manual covered only AN/PGC-1 and the TT-4A.TG and 
B/TG.  The later ones also cover the TT-4C, AN/PGC-3 and several higher TT- 
numbers.  

I also have one original (not for sale) of TM 11-5815-206-12 dated 1959.  
It might be useful for the photos in the PDF.
