Alan,
I think you might be able to go up to 1966 with that,if you're doing course II anyway,its section E on the paper isn't it?
"Wing Over Ireland",The story of the Irish Air Corps by Donal MacCarron is a very good book,very comprehensive,I couldn't tell you exactly where you could get a copy though,try easons and some shops like that i suppose.
Good luck with the leaving btw,its a bitch alright, I'm doing it too!
