Interesting one. I checked a few site si have saved, including one that supposedly has the serial of every B-17, but found nothing. I did come up with a little info on some other sites. It crashed near Daventry on 15th Dec 44. The pilot was Finis E Harries. The group code was a G in a triangle, but I guess you know that.
The 305th site isn't much help. But i'll see what else I can find. Not knowing the nose art is a bit of a bummer.
I am a Norfolk man and i glory in being so
