[GreenKeys] Sperry Combination Teletest

[jgras at att.net]

I recently obtain a TS-800/UGM-1 Teletype Distortion analyzer.  The
Tobyhanna certification tag on it references a manual TM 11-6625-620-45-1.
Does anyone know where I can find a copy of the TM?  I got of copy of TB
11-6625-620-35-2 Calibration Procedure with the unit, in case anyone needs a
copy.
