I flew on this aircraft recently :

I noticed while in the cockpit that her previous reg was 9M-MFD as it hadn't been painted over (look under the clock, to the left of the FMC) :

Now here's the catch : 9M-MFD's msn is listed by Charles as 26448/2484, whereas I am sure that F-GJNZ is 26450/2503
So what gives ?
