There were some advertised for the equivalent of £32 without the OCXO (and
free shipping). Seemed like a good deal so I bought two.

I have  been watching this thread and may have missed something. My
questions:  What is the purpose of the outboard OCXO VECTRON 63.8976Mhz? 
What model  number does this RB most closely resemble?
 
-----------------------
No purpose other than a bit of gamesmanship.
When first listed these auctions were categorised as "New", but if you
looked at the small print it was the throwaway oscillator and/or 9 pin
connector  that were new but the RB module itself was indicated as used.
 

The module is just one variant of the FEI FE5680A, in this case the PN is
217400-30352-1 and the frequency can be adjusted over a small range using
HEX  strings that have previously been documented on this list, in order to
set it  accurately to 10MHz.
