Hello Edward
It seems like there is not all that much on that fellow and the best that I can find on him is what Neil Page published at the following
link. I have only seen one of his victories which happened on 24 October 1944 when Gefreiter Erich Brunotte of 13./JG 51 claimed an Il-2 m.H. at 12:23 at Pl.Qu. 13 342 at 500 meters as his first victory according to Prien. Of course, this is when the claims lists basically begin to end so his total is somewhat in doubt. Hopefully others can add to this.
Horrido!
