[Collins] Beckman frequency measuring system

[Bill]

that is a grey faced 51j-4.  Not sure if it is the rare (much sought after)
grey face one or not. Sure looks nice.

Looking for information re a Beckman frequency measuring setup that is 
basically a rebadged Collins receiver  (51J series-not sure just which 
model- any suggestions?) and two associated units. One is called a 
'Translator' and has a scope for zero beat display plus a speaker and 
is full of tube electroincs. The other unit had a frequency readout 
made of neons and a quartz frequency std etc. This latter unit is 
missing now but the system is still quite useable with a HP 5245L 
frequency counter as a replacement.
 A couple of pictures here -  http://homepages.ihug.co.nz/~tractorb/beckman/
Particularly interested to find out when this system was on the market 
(suspect early to mid- 1950s) and any info re price etc. Scans of 
catalog info would be especially welcome, as would system specs and 
pictures of the missing display etc.
