Ah yes, G-SOLO, forgot the one that parted me hair! RKSF made up the four ship with the 'BGS* team.
Think you are right, G-BDKS replaced G-BAEA, and G-BECM certainly was around in Rothmans scheme at one point...
Presumably G-BADY was one of the Fleetwood mid air collision aircraft.
As Aerohack says, Cliff Barnett survived the Pitts crash but was sadly lost along with Steve "Propliner" Piercey after their photo mount (an Aztec?) collided with a Beech 1900 at Hanover. Was privileged to meet Steve a couple of times, a super bloke. Last saw him a week or so before his death. I may still have Roger Bacon's tribute in Flight to the pair in the loft... Total Aviation People, the ultimate Bacon accolade...
