Hello,
effectively this plane was already involved in an accident before as a Bf 109 F-2 (JG 51). Upgraded? Maybe, does it mean they changed the wing label? I have no answer, but I wonder why should they do.
Gilles one good stuff here:

I have some pictures reputed taken in St. Jean d'Angely (Bf109Fs) but eBay - without antifuchs - and quite small.
A+ Franck.
