He was Stab II./JG 3. Strangely, the RK book says he had 6 kills in France and Battle of Britain, none of which are listed in the books and the only place I have found linking him with that day is in Foreman's 1941 Part 1. Michalek came to 4./JG 3 on 15 Jul 41 and his first kill was the following day and numbered 12??? Look at this:
