BS, you can be as piccy about the piccy as you like, but the original (much larger) JPG image clearly showed G-REDK and the French test reg as F-WWOM up on the engine cowling. Down on the tail is "BAS002", the internal ECF code for the second aircraft in the order, consistent with REDK being the second in the J to N series. I expect that both the factory code and test reg will be removed by the time it enters UK airspace.
