COMTECH EFDATA 10MHz module with OCXO VECTRON C4710

[Iv3xkv]

 I have a nice  surplus 10MHz reference generator module dismantled from unknow equipment.
It is marked COMTECH EFDATA  PL/0014-5 .    I would  like to test and repair it to reuse.
Have someone  informations about this module and the connecting scheme of his 8 pole  connector?

On the module is installed  a 10 MHz OCXO VECTRON marked as C4710C1-0021   27318-0061  0822. In the VERITRON web site is available  the   datasheet of  the C4710C1 but  it is not clear  the meaning of part-number extension (0021   27318-0061  0822) that, I suppose, define  the version. Can someone   help me to understand detailed specs of this  OCXO?
