Rémi,
After a closer scrutiny, the second pic of München-Oberwiesenfeld airfield does reveal in the foreground IMHO a Mtt built Bf 109 G-10. Tell tale sign is the the lower engine cowling with small bumps,and the fuselage camouflage which does not cover it fully, like for the Flössenburg produced Bf 109K-4's.

The W.Nr. is present on the lower third of the rudder, unfortunately damaged. Only the last digit can be made out as a 7.
Cheers
Marc
