For what its worth or whomever might need, I have a set of ARC manuals that include the original Type 12 ARC factory manual, as well as manuals for the ARN-30 and for the later ARN-30A, B, C, and D.  I do not have the capability to do complete manuals but can do discreet pages.  I was once an avid collector of ARC stuff and worked on acft with this equipment installed.  A long time ago but those were the days...

Hi Everyone
 
Lots of people responded to my email -- Thank you!.    I think I have my questions answered, but I am still unclear on some things.
 
This is the radio I have:   R-13B aka R-445 AN/ARN-30.
