Hi all I'm currently working on my family tree and am trying to locate war photos of Flugzeugführer Fw Günther Liersch-NJG 6, Fw. Walter Preißler, Bordfunker and Bordschütze OGfr. Rudolf Kelle and their night fighter. Fw Günther Liersch shot down Lancaster PD322 of whom one of the crew was my relative.

Im also trying to locate photos of Lancaster PD322 and it's crew. It would be awesome to have the crews from both sides for my family history.
Any help at all please.

Thank you
