B-17 Crash 20 Jan 1945 near Guisberg, France?

I am attempting to find the name of a B-17 that crashed near Guisberg, France on 20 January 1945.  It had become lost in the heavy overcast skies and the crew bailed out.
 
Any suggestions on where to look?  I don't know that MACRs would help because the plane crashed in Allied held territory and the crew members were probably all recovered.
 
Thank you
