Who flew this Bf 109F from III./JG 77?

[Parabellum]

I believe we are working in a wrong way, with Blaurock or Pichler.
Both of these pilots were members of 7th staffel_III JG77.
Complying with the german rules of fighters markings, the tactical numbers of 7th staffel had to be painted in white color, as for instance, on Wolf Dieter Huy Me.109-F.

In the present case, the tactical number is either red or black (no matter which colour, in fact), denoting an aircraft of the 8th staffel.
Indeed, who was flying with this red or black 2?
