Kari, The match for JG54 was already done on
www.bellabs.ru/51/ . Leykauf was the only one that I could find to match that day in JG54. As far as the grids go, I tried to get someone to locate one that should have been in Russia but came up in Poland. Maybe it was an error on the grid or the person with the 1GMTAP history but they were a naval bomber unit hitting naval and transport targets. Maybe the answers can come up on this thread.
Best regards,
Nokose
