[Milsurplus] Looking for PRC-77 Schematics

[Al Klase]

Guys,

I've misplaced my PRC-77 drawings.  In particular I need the schematic 
for the A54 squelch module, but the whole TM would be most helpful.  
There's a .pdf of TM 11-5820-667-35 floating around on the web, but it's 
the C3 (Change 3) version that has the bulk of the schematics deleted.  
If you know where there's a pre-C3 file, please let me know.

&3,
Al
