Since the readers were so helpful previously, I hope that you can help again. My father, a RAF CPL F2A, was posted out of ECAS/EAAS to 4ACPC(a) in September 1945 and back to EAAS 10 days later. I have not been able to find 4ACPC(a). Even though the "P" is perfectly clear on his records, could it be an error and actually be 4ACRC(a) which is Filey? The internet didn't help me much to know what Filey was during WW2. I got the feeling it was holding area, could it be like a PDC?
