Thanks Martin and Alain57.
The German loss details I have from WASt/DD/BA:
1941-02-04, 2./NJG 2, Do 17 Z-10, 50 km östlich Lowestoft, 34 km südöstlich Norwich
Flugzeugführer Olt Häuser, Otto, +
Bordfunker Fw Palm, Gerhard, +
Bordmechaniker Fw Quade, Johannes, +
Vom Feindflug nicht zurückgekehrt
So the KG 2 aircraft Alain57 mentions must be a different loss.
My experience of working with RAF archival material is rather limted so I really appreciate any help or leads to track down the RAF counterpart for this encounter. Since a victory was achieved I would assume that it would have been documented in various ways, at least if the crew were aware of the outcome.
