Not of any relevance to the OP's question, but I thought I would post this out of interest as an indication of the affects of inflation over the years
I left the RAF in January 1977, a few days after my 30th birthday. As I had left under the terms of the 1975 redundancy scheme I was entitled to a pro rata pension, payable immediately. This was calculated at 9/16 of the pension which would have been payable at my 38/16 point, and came to £68.08 per month. I was paid this amount monthly until my 55th birthday, when it picked up all the intervening increments. I now receive £479 per month, which looks a lot better than £68.08, but in real terms it is probably little different. Incidentally I have been receiving a pension for 41 years now, 29 years longer than my period of service. I know that when I was first commissioned I was the youngest officer in the RAF, and I sometimes wonder if I was the youngest ever RAF pensioner!
