Hallo Rammjäger
I am not sure why you "desperately" need to tie in Victor with the Victim?
This is extremely difficult to do due to overclaiming on both sides and loss of relevant documents.
The combat on the 19th was fought between seven Hurricanes of 33Sq and five 109's from 8.+9.St/JG 77.
The British claimed 4 shot down + 2 damaged while loosing 2 of their own
The Germans claimed 3 shot down, while loosing 3 themselves, incl Ubben, who was reported as falling to Flak, and Armin Schmidt killed. Note that Shores makes a mistake regarding losses in this combat and, this is corrected by Prien in his JG 77 book.
The combat on the 20th involved 29 109's strafing Eleusis and Tanagra airfields. In this combat Pattle claimed 2 shot down while the Germans lost 3. Since only 1 Bf was lost 100%, the other two belly landed back at their base Larissa, it is almost 100% certain that the black 10 was Wnr 3282 flown by Fritz Borchert. Claimed by Luftwaffe as lost to Flak, it seems much more probable he was hit by Pattle's fire. Shores claim the aircraft belly landed at Larissa, but this cannot be correct since that field was held by the Germans at the time and pictures clearly show the aeroplane to be investigated by British troops.
The individual marking on black 10 is indeed strange. I have seen it sketched somewhere, but cannot recall where and certainly not if the artist had got it right or not.
Cheers
