According to Theo Boiten's excellent work the Nachtjagd War Diaries (Edition 2008), two pilots are listed as possible's for the loss of this 100 squadron Lancaster ND571.
The first:
Hptm. Julius Schurbel 4./NJG5 over Standel. 6.000 Metres Time: 03.03 hrs.
(Total of 2 claims - killed 02.03.1944 in a non-operational crash near Spornitz.)
The second:
Lt. Joachim F. Hanss 1./NJG5 Stendal area 5,400 Metres Time: 03.36 hrs.
(Total of 11 / 12 claims - killed on 7/8.07.1944, shot down by a Mosquito from 239 Squadron.
Hope this helps, although may just add to the confusion for you.
