Crash B17 at Lokeren on 5 nov 1943

I am doing research on a crash of a B17 at Lokeren, Belgium on the 5th of November 1943. The plane was shot down (±14.00hr) by a Focke Wulf.
It was AC nr. 42-30789 (Flak Suit or Butcher Boy) with pilot Lt Bramwell.

I have two questions: is there someone on this forum who have more information about that Focke Wulf plane and pilot?

The second question is more complicated and maybe not for this forum , but anyway I try: Two crewmembers were death. The German autority give two names to burried them: T/Sgt Harrenstein and T/Sgt Kenneth D. Shaver (tagnr 34036141 ). But it was not Shaver in that plane. It was S/Sgt John Craig who was killed. Shaver was a member of the crew of a B17 with nr 42-3014, that was shot down the same day in South Holland (Zeeland). How its name comes on the Kommandantur of Sint-Niklaas?

You see, we have a problem here in Lokeren.
My best regards,
Andre
