I'm still going for one of the B9's on the Red Arrow or Fab 56
Assuming Bus Times is correct, the only 2 vehicles it could be are 6050 or 6064. 56 B9s are ruled out unless they add in the extra light (which is possible, but doubtful).
I doubt it's 6064 as they'd still need to run it alongside the other Coasters so it makes sense to keep it as it is, plus it's still a fairly recent paintjob.
My money would be on 6050 as they're due to be replaced fairly soon.
The big question is what can they do with a base green livery on a route it might move to?
