This one has stayed on my mind for a while as well... I read Heinz Knoke´s book a while ago, and it had a little mention on pilots with FW 190 ( probably Ta 152 ) whose plane´s front window was bullet proof glass, and probably had heavier armament than normally. They also had a sign on their planes and jackets, two big eyeballs. This is because their mission was to attack the B17´s face-to-face and open fire only when they see the pilot´s eyeballs. Anyway, I´d like to hear more of them if possible. I tried to pinpoint them, possibly III/JG 54 ? I´d be thankful for all the information I can have!
