Hallo Dave,
Lt. Hans Bott was with JG 400, has one "Abschuß" of a B-17. He is very familiar with the stories about JG 400. He wrote, that there were not as many kill's by Me 163 as claimed or reported by bomber crews.
He is a friend of mine and now leaving in Argentina. He was like me with Schulungslehrgang "ELBE".
You can contact him:
hansbott@gmail.com
I hope I cold help
Fritz M.
