Rick Barbera Questions License Number Coding

I was with the 5th RR and later the 1141st SPACTRON, from February
1955 until November of 1957.

I have a question. I remember two license number
designations .... SF which stood for SHAPE FORCES. My plate number
was 7711 SF. There was a CF designation also. But I don't know
what the CF stood for. Do you remember, or can you find out?

`I would appreciate it a bunch.

Thanks,
Rick Barbera
