Chris, I did NOT say it was the sole machine from I Gruppe of KG 51 to have flown during the winter of 1942-43.
But, the information available do points to a SOLE Ju 88 C-6 flown by I/KG 51, between October and November 1942.

The werknummer and codes of this machine are unknown, hence my theory or assumption that THIS machine with solid nose, spinners possibly yellow or white but very weathered (the spinners are darker than the Edelweiss emblem), coded 9K+F? (underside of the wings, close to the wingtips are yellow too); photographed on the Eastern Front (most possibly either at Tazinskaja or Sarabus, may be THE Zerstörer Ju 88 flown by I Gruppe during this frame of period.
I guess you misunderstood what I wrote.
