Airmen of 2nd Reconnaissance Squadron, Albatros C.X 9259/16 (CWL 4.1). At the background early CWL propeller with visible decal and non typical 6-pin hub. As confirmed by several sources Mercedes D.IV engine was fitted with 8-pin hub. Could it be a kind of modification done by the CWL workshop? Picture taken at Kowel Airfield between 17^th and 27^th July 1920 as reported. Picture from Feliks Przystupa collection, presented in Cultural Centre of Łęczna. Thanks to Robert Gretzyngier, who sent us this photo! (entry: 1921)
