That is another one. The Two machines with the reservations have nothing to do with the one of the Early Birds. But a reservation for a registration is just that, this not indicates that a P51 and P40 are indeed coming.
And this is not the first time a reservation for a 51 has been entered. A guy named Groenevold (sp?) reserved PH-MMF 20 years ago according to an old Flypast. Anyway, Coert Munk is a member here, so maybe he can shed some light about this recent development on the Dutch register.
