I contacted one of the MTI Milliren marketing guys a few days ago, and got 
some specs on the MTI model 260-0624C and 260-0544C OXCOs that are currently 
being sold on Ebay.  the model 260-0624C is the one used in the Lucent 
/Symmetricom Z3810A systems.
The model 260 is advertised as being close to a Rb in performance.  This is 
all the data that he would give me since I wasn't the original customer for 
whom they were made.  He also says these models are still in low volume 
production for the customers.

260-0624-C 5MHz, SC- cut crystal, 3rd overtone, 2E-10 over 0 to +75C
Phase Noise spec:
-100 @ 1Hz
-130 @ 10Hz
-145 @ 100Hz
-150 @ 1KHz

-155 @ 100KHz

Also, the 260-0544C
260-0544-C 5 MHz, SC-cut crystal, 3rd overtone, 2E-10 over -30 to +70C
Phase Noise spec:
-110 @ 1Hz
-140 @ 10Hz
