There are two, that I know of (there may be more than one release of 
each -- I know there are at least two releases of the 1962 manual):

1955:
Army TM 11-856  (*not* TM 11-856A, which covers the R390A -- thus, TM 
11-856 "not A"...   ;-)
Air Force TO 31R1-2URR-154

1962:
Army TM 11-5820-357-35
Air Force TO 31R1-2URR-412

I believe there were 4 field change orders.

Best regards,

Don
