Karl Waterbeck KG 40 Fw 200 and He 177

[Hindhead9]

I am searching for information about the Luftwaffe career and any other details or pictures of Oberleutnant Karl Waterbeck born in 1915 in Coesfeld Germany and his crews. I understand that they flew Fw 200 Condors with KG 40, possibly out of Trondheim-Vaernes Norway, before retraining on He 177's at Fassberg in 1943. Waterbeck was shot down and killed in He 177-A3 Werk Nr 535747 CJ+FU, F8+HH at Whitmore Vale in England on January 21st 1944 in the first raid of Operation Steinbock. His was the first He-177 shot down in England, and his aircraft was brought down by the 151 Squadron Mosquito crew of Howard Kemp and Jim Maidment. His crew at this time was: Ogefr Jann Bikker (POW), Ofw Erwin Marbach (POW), Ofw Georg Six (POW), Ogefr Werner Doge (POW), Gefr Johannes Conrad (Killed). He was awarded the DKG in November 1943, but as he was transferred I understand for He 177 conversion in early 1943, I am not sure if this was for earlier operations with the Fw 200 or subsequently with the He 177. He appears to have flown with Oberfeldwebel Jurasch (Bordfunker) whilst in Norway, but am unclear if Jurasch was in his crew on 21st January 1944, although it appears that Jurasch was interrogated asa POW in England with Intelligence noting his and Bikker's morale was high.
