Sorry not been any where near Luton, must have been like it when it finally left MAN, maybe the rudder was in neutral when you painted it, or the picture is with a little rudder input.
It's either a trick of the light or some work has been carried out after painting. We only paint the diamond as these are yellow, the rudder is at full defection when painted. The circle on the rudder section has also been cutoff with a white section through it.. Not the end of the world but a bit annoying.
