Thanks to a loan from Brown W1NZR, I have scanned and posted the 1963 USMC Maintenance and Overhaul Manual for the AN/PRC-47. 

FWIW, it appears to be somewhat different from the Army TM found on line. This is a 1977 Govt Printing Office reprint so the photos aren't as good as the original manual was - if anyone has one with better photos that I could borrow to scan, please let me know.

Cheers,
