Certainly not an exhaustive search, but the '93 report (as early as I could easily find) has annual increments (for us Rodneys) (P20). Baldricks got triennial daily rate increments(?) (P21)
Twenty-Second Report 1993
It also includes figures from '92 report (P22 & 23)
Wingcos & GCs got biennial inc. rises, Air Commodes no increments.
