A mate who completed 13 years and left as a Junior Technician in 1975 now gets £250 a month. He claimed it a year too late but got it backdated.
I left as a JT in 1971 after nine years (plus 2 before reaching age 18) but as far as I'm aware I have no pension entitlement as the rules back then said pensions were only payable on completion of 22 years service. I know there is a group who have been fighting to get this changed but without much success.
Apparently parliament cannot change it retrospectively although I hear they managed to do it for MPs?
