Nick,

Here is a page on the CV-89:
http://www.prc68.com/I/CV89A.shtml

I have a picture of the CV-89 as part of the URA-8 (which had two CV-89s 
and a comparitor in one cabinet) along with an RBC receiver. I'll forward 
that picture to you off-list.

I don't find the manual for the CV-89 in digital form, but I do have a copy 
of it, along with two examples of the thing itself.  I don't have the 
comparitor or the cabinet that housed all three.

According to the web page above, the manual is:
T.O. 21R1-2URA8-11 Frequency Shift Converter-Comparator Group AN/URA-8B and 
Frequency Shift COnverter CV-89A/URA-8A
1 Dec 1952, Change 1 1 April 1975.
