Most sources say that 42-30048 was captured more or less intact in Laon area.
According to the website
http://francecrashes39-45.net/rech_avion.php, the bomber that crashed in Gouchaupré was 42-30037.
5 B-17s (all of 384th BG) were shot down during the mission, while German pilots made 6 claims AFAIK, so close to the mark: at 1805, 1810, 1830, 1844, 1854 and 1901 hrs.
If you can find Allied reports, these claims are over one hour so it could be possible to link losses and claims. But it is fairly possible that two bombers fell in Dieppe area to Priller and Goltzsc.
