Hi there gang's boss!
I am going to say a stupid thing
but the following one is in same range and it's a Schwarze 7 too. Of course the mountains in background don't make us think to Belgium; whatever ...
And I didn't say it's the same plane; just an element of possible answer.

JG 27 sounds strange with that similingly Yellow band.
Cpt Farrels did make a profile of a G-10, "Schwarze 13" displaying such dark (two tones) camouflage and such yellow band talking about a JG 11 aircraft.
Cheers, Franck.
