Bizarre or not, but I've got corrected info on this from Tony Wheeler, Air Britain's Commercial Scene Editor.
He states that the change took place from 00.01 2 July 1987. I tend to trust him bearing in mind his position and he's also quoted the last aircraft he saw on 28 - an Air Atlantique DC-6 (G-SIXC) at 20.12 that night.
