1974 - interesting. But two things strike me - firstly, we need to include SAM Sqns and the RAF Regt Field Sqns - and second, even back in those halcyon days, the amount of strategic transport and rotary wing transport was inadequate for expeditionary warfare - showing that the current unbalanced force structure is nothing new.
The next question is what is (a) the "right" size for today's RAF, if we were spending 30% more than we are now and (b) within the same amount of cash - ie trade offs - what would the appropriate front line look like?
