6.(F)/122 had at least two earlier F6+DP:
Ju 88 A-4 (W.Nr. 550203, F6+DP) shot down on 9 August 1944
Ju 188 D-2 (W.Nr. 150044, F6+DP) shot down on 28 November 1944
We had a much lower quality shot of the Innsbruck machine in Air War Italy 1944–45 (I don't recall the source) and the "DP" was about the only detail you could make out.
