They look like APKT33 inserts. Those are listed in Shars catalog (page 94) for face mills. Shars shows the (ISO #) APKT160408 PDER at 0.551" or 14 mm.

I looked at them they have raised cutting corners, my cutter has positive cutting reke, the inserts are flat with chip breaker
 
They make this insert with many different configurations of chip breaker, positive/negative cutting geometry, and so on. The more common insert is the APKT style as Bruce mentioned above. The one you show in your picture I'm sure was designed to cut a certain material like cast iron, which will have a more neutral corner to the insert than the APKT has. And no, I have no clue the letter configuration for you insert. I bet the APKT style insert will fit the face mill you have there just fine.
 
How about the cutter, if there are any designations on it you might have better luck with that in finding out what type & size inserts it takes.
 
The cutter has no markings at all, generic black 4 flute cutter
 
Could you post some pictures of the cutter and the pocket to give more information of what you have?
