Hello,
Currently on ebay is a photo album captioned as coming from Flieger Abteilung (Artillerie) 207 at:
https://www.ebay.fr/itm/225885859829...8AAOSwArRlX2Jq
While I don't think it compares with the Jasta 12 album a few threads down on this board it may be of interest. The aircraft photos which include a few easily identified entente machines,are at the beginning and end of the slideshow. Many of the German aircraft are either captioned Flieger Abteilung 207 or bear the chevron markings associated with that unit.
Regards,
Clint
