Lancaster LL922 7/8th August 1944

[jonathannex]

Hello there,
I'm new to this site and have been told that this is a fairly common request! I'm trying to establish which pilot shot down the above aircraft, a 50 squadron Lancaster marking VN-E. The aircraft was lost on the night of 7/8th August 1944 at approximately midnight during the Sequevile raid. The Pilot, Navigator and Wireless operator died but the remaining crew survived. The crash site was near the village of La Frenaye in Normandy. Although this was a large raid only ten Lancasters were shot down. From the information I can find there appear to be two Luftwaffe pilots who may have shot down the aircraft. They are

1/ Uffz Koch of 4/NJG4 Ref 2025/I Anerk [ Certificate ] 56

2/ HPTM Hubert Rauh STAB II/NJG4 Ref 2025/I Anerk 23

Please could anyone shed any further light on this ? I'm not sure if a crashed aircraft would be associated with a particular Luftwaffe certificate or if the combat reports for these actions would still exist. Any help would be much appreciated. Thank-you.
