Salerno,
A post on armyairforces.com reveals some more info:
http://forum.armyairforces.com/Unkno...2-m214047.aspx
Here Prchal's B-24 is identified as "59-W".
Note that 376th BG lost another B-24 on 11 Jan 43, the one of Lt Col John Payne, so the sergeants I mentioned may have been on this plane instead.
Regards,
Leendert
