[GreenKeys] Speaking of Military Teletypes (Teletypewriter Reperforator T...

Paul,

To take your last question first, no.  Field Grade is, if I recall 
correctly, Major through Colonel.  It has nothing to do with equipment.  F means 
"Fixed" and "G" means Telegraph or Teletype.  See "AN Nomenclature System", 
"JAN" or "Joint Army Navy" or similar.  Although I think it has been abandoned 
for the most part, it applies to electronic and some electrical equipment 
including most mechanical parts thereof, and dates from late 1942 or early 
1943.

I think the QTH.Net server will strip it off but in the direct, see the 
attached PDF from 1959.  I have a later one but don't have time right now to 
convert it to PDF.

I suspect that maintenance on the TT-107 et al is covered in some manual on 
some AN/TGC-xxx set which I don't have time right now to try to track down. 
 The two parts manuals are the only entries that I see under TM 
11-5815-257-nn.  If I turn up anything else, I'll post it.
