Hi Don,
possibly JG 52 book will have some data in it.
as for the USAAF, U probably have it...but:
STRATEGIC OPERATIONS (Fifteenth Air Force): In Austria, 760+ B-17s and B-24s, with fighter escort, hit the Korneuburg and Kagran oil refineries, the marshalling yards at Wels, Sankt Polten, Amstetten, Wiener-Neustadt, and Klagenfurt, and the tank works at Steyr. Routine supply, reconnaissance, and escort missions continue. The 885th Bombardment Squadron (Heavy), 2641st Special Group, moves from Brindisi to Rosignano, Italy with B-17s and B-24s (the squadron transports supplies to partisans and drops leaflets).
