If I remember correctly, it had a white cabin and blue tail. (Could have been the other way around.)
Nope. It was definitely blue and white in equal measure.
Liverpool to Blackbushe definitely sounds like it would have been N510W. Colours look like they were probably right too.
With Si's positivity, I guess she has had a recent paint job?
If I see it again I'll train my six mega-pixels at it and try and get the reg.
I think the 430 is probably the most likely candidate, but I'll take a closer look at the top cowling if I see it again.
...and had the reg moved and reduced in size!!!!
