Retired Pay + C.S. Salary.
Heights good,
For what it's worth, I retired Jany '73 and kept full RAF pension when joining HMCE following month. Retired from HMCE 1986, been drawing their pension as well for 26 years now. Have drawn far more from RAF in pension than ever they paid me in 23 years service !
Long time ago, but would expect principle to remain the same. Good luck !
Danny.
