Hallo again Alex
Yes rather certain the victory was scored between 14 and 28 Sep 15...!
The Heeresberichte gives some clues of the date. With the information I have from that and other sources at moment,
a possible date is 22 Sep 15.
Looking at the personal roster I have for FFA 22 at that time a possible candidate for pilot is Uffz Fritz Kosmahl...
I dont knew the dates for his two first victories..
However to get a definite answer you must search sources I havent read yet. In this case you must read the daily reports
of AOK 3, they with certainty exists in more then one German archive. The Stofl 3 and others Stofls
did not write own weekly
reports at this stage of the War.
However I have a German contact who probably have read these AOK 3 reports. I will send a private e-mail with his name so he probably can help you.
