Afaik, only II./JG51 was operating in Hungary, while III./JG51 was in the area HG Mitte / HG Nord, Southern Baltic states in late summer '44.

The losses due to enemy bombs were due to an air attack on the airfield of Ezere. One A/C from 9./JG51 with Uffz. Hans Bauer was lost in an Alarmstart. Ezere sounds rather baltic to me
Digging a little further... if you really talk about the six Boston-claims by III./JG51 on 22.09.1944: These were in a fight against 1 GMTAP KBF which had 3 losses. KBF stands for "Krasnoznamyonnyy Baltiyskiy Flot".
