Record of Service? hahahahahaha ... I handed in my F1250 after 30 years, and got a couple of cut-and-paste letters from my AOC and PMC (Barnwood, not the mess). All I have is my RAFA "Retired Service Card" annotated as a Life Member. I suspect actually generating proper, official, proof of service would be a paper-chase. Anyway, that's all in the past, I don't wear medal ribbons on my pajamas or use my former rank. It's over. <Sniffle>
PS: I suppose my ATC Certificate of Competency (F5994?) would suffice, although that only shows when I was an operating ATCO.
