Many thanks for that Lyric. I'll have to do as the authors have done, and look for the dates of raids on Politz.
The previous page describes an attack on a Mossie by Gerth in his 163, with one crew member baling out. I've no loss I can match it to for November, will have to snoop around a bit. I've one unexplained loss of a recce Mossie in September, with one POW, however I don't know if the 163s were flying then. Gerth seems to have been on 3./JG 400 from September, but it's all a bit tenuous.
Many thanks again Lyric, much appreciated.
