Hi Eugen
Magnus' Aces List at
http://users.accesscomm.ca/magnusfamily/ww2usa.htm has Lieutenant Colonel Jack Junior Oberhansley credited with six victories while serving with the 14 PG, 78 FG and 4 FG. At
www.web-birds.com/8th/78/78th.htm he is listed as having claimed one victory with the HQ and five with the 82 FS of the 78 FG. If this information is correct then he must have been serving with the 82 FS at the time he shot down Tratt. Any comments or corrections would be greatly appreciated but perhaps this might help a little.
Horrido!
