Dragontech:
I meant to add that I thoiught the profiles were a great effort!
There are at least two (possibly three) more 2 FTS "Blue Chips" aircraft:
WG348/28
WG478/20
These are based on photos I have. There is also an intriguing Air Britain spotter's report on an airshow in the UK (courtesy of Geoff Ambrose) where WG478 and WK507/36 were present as representatives of the "Blue Chips", although whether the latter wore the blue flash/unit crest device is open to conjecture. Certainly this was removed from WG478; there is a 1974 photo of her re-coded as "30" (in quite diminutive numbers as well) showing no sign of the blue flash.
