Option 4C is not listed in the manual, but presumably it refers to the 
timebase.  You will be able to tell best by looking inside when it 
arrives.  Racal made a lot of different ovens of different qualities as 
well as TCXOs.    All the US military had were the 1300 MHz version 1992 
counters with a very good OCXO inside, type 9462, so yours is a civilian 
one, I'm afraid.
