Hello everyone,
Lately I obtained two AF filters. One is marked as: 

    FILTER BAND PASS
    5915-99-920-1117
    500 C/S  TX & RX

The other one:

    FILTER BAND PASS
    5915-99-920-1118
    700 C/S  TX & RX

Dimensions about 8cm cube and with a DB-9 male connector fitted on top.
As they are painted in the well known RACAL RA-17 green I suppose they are RACAL origin. 
I have measured the B/W and it's about 180Hz by 6dB when connected to
600R.

Anyone in the group who knows more about this specimen?

Best regards,

Guido, ON6RL.
