12./NJG 1 losses on 1 September 1944

[Lucky Luke]

Hi all,

Further to my request about the claims and victories by 83 FS/78 FG on 1 September 1944, I am seeking the crew names of the three aircraft that were shot down. The Bf110s shot down by the American P-47s were discussed in posts on this forum in 2009 and 2013:

However, some of the crew details are incomplete.

Bf 110G-4 WNr.740242 12./NJG 1 G9+LZ
Pilot Oblt. Eberhard Koltermann wounded
Is it correct that Oblt Koltermann didn’t score any victories at all? Is it a common occurrence for a Nachtjagdpilot not to score any victories?
Bordfunker Uffz. Rudolf Stiening wounded but possibly died of his wound 3-4 September 1944. Is this correct or could this be another person with the same name?
Bordschutze Ofw. Johann Poppelmeyer killed
1.Wart OK. Is the name of this fourth occupant known?

Bf 110G-4 WNr. 740647 12./NJG 1 G9+GZ
Pilot Uffz Anton Krebs, Uffz Robert Schmalze, Obgefr Rolf Tröster, Obgefr Ernst Klöber (1. Wart) : all seem to have survived the crash/crash landing.
Was Schmalze the Bordfunker and Tröster the Bordschutze?

Bf 110G-4 WNr. 740246 12./NJG 1 G9+FZ
Pilot Oberfähnrich Wolfgang Schubert, no further details about the other occupants but reportedly all died in the crash. Are the names of the two or three other occupants known?

One additional question: I have the 1999 edition of Michael Balss 'Deutsche nachtjagd : Materialverluste in Ausbildung und Einsatz' and seemingly, this book does not list the three losses above. Are these really not in that book or do I need a new pair of glasses?

Thanks in advance for your help.
