You have two "additives" which don't sound very useful. It might be a starter or a regenerator or something.
They are for the RA-4 process which is used for processing color paper. I don't know that they'd be of much use to you unless you used Trecom RA-4 color paper developing chemistry.
I can't make much out of those designations either; they must be special additives for certain processing situations.
But anyway, you could call CPAC; both products are still listed.
