Yes. The two receivers differ (aside from any serial number related changes 
during production) only in the nameplates. The electrical differences are 
in the antenna relay, junction box, and dynamotor.

Yes.

Yes. The Command and Liasion receivers are not interchangable but the 
coilsets are. 

I have the manuals on GF-11/RU-16, GF-12/RU-17, and RI-18 and 19 available 
as reprints. I also have a few earlier manuals but haven't scanned and 
cleaned them.
