RBZ 5459 wroteAny orange bumper, in fact orange on the front in general, is now obsolete after updated paint specifications were released today.
Saw 19683 being returned to Walkergate in the new livery today and, yes, there is no orange anywhere on the front. Below the windscreen there are two white panels and then the blue bumper. It also has the 'panda eyes' front headlights.
