[GreenKeys] Teletypewriter Reperforator TT-109/FG -- Seeking TM 11-2228, TM 11-5815-257-20P, and TM 11-5815-257-35P

Duncan:  Thank you for the TT-76 tip!  I as yet know *nothing* about
Kleinschmidt gear; while functionally equivalent to Teletype it’s pretty
clear that they have quite different mechanical designs from the Teletype
M14 / M15 gear that I’m currently learning.  So I’m trying to get smart
before I touch the wrong place at the wrong time in the wrong manner :->.  I
didn’t realize that Kleinschmidt documentation was a problem
across-the-board; assumed that I just managed to get unlucky with my
particular equipment!

Looking briefly at those documents, the -35 is the valuable low-level
maintenance publication.  In none of the documents do the overall mechanism
illustrations look reasonably similar to my unit, however in the -35
document a number of detailed illustrations are clearly related (e.g., the
selecting-and-printing functional diagrams) and likely the
selecting-and-punching mechanisms diagrams as well.  Seeing the various
circuit diagrams is also helpful in confirming what I am seeing.

Paul,

Yes, TM 11-2228 is hard to find.

However, the TT-109 series is basically a "RO" (receive only) TT-76. The 
TT-76 manual is TM 11-5815-238-xx. They are available at 
http://rattrig.com/manuals/tm's.htm 
The xx is : 10 = operator manual; 20 = low level maintenance manual; 35 
= high level maintenance. The "P" suffix denotes a parts manual.

have fun,

Duncan
