Hello Thorsten, Rammjaeger, and Lolok,
Thank you all very, very much!!
Lolok, I really appreciate your wife's help! That cetainly will be very useful.
Rammjaeger, I have a very good idea about Kwilecki, but I would still enjoy 'hearing' your input.
Thorsten, the family crest of the Kwilecki family is a treasure!! I had seen something similar in Puglisi's notes in the Ferko archives, but your image confirms that the Wappen on Gluszewski's Fokkers was red and white. I am extremely grateful.
Here's our friend, all suited up with Heinecke parachute harness and ready to go on Escaufort airfield, 5 September 1918:
Here's another example of his signature.

He was commissioned in the 3.Garde-Ulanen-Regiment, as were two of his comrades in JG I,
Georg von der Osten and
Viktor von Pressentin gennant von Rautter.
