Hey, there! Do you still need that information? i thought that i'd be helpful since you helped me out. well, that and the fact that i love the B-17.
I have a few references on the B-17, but i think the insignia changes location depending on the time period, so which insigina is available, the circle star with the red dot (Pre-1942), just the circle star (1942), the circle star with wings and red lining (1943), or the blue/white circle star with wings? Is "Thunderbird" the aircraft name? I'll try to dig up some pics.
