Hi Rainer,
I think the identification by Dan-San is right but accidentally he mixed up numbers. The Nieuport on the photo is B1523.
It belonged to a flight of 60 Sqdn. RFC which was engaged on 14 Apr 1917 near Gavrelle. The unlucky pilot was 2Lt. Lewis Carlton Chapmann, who died of his wounds two days later received by Vfw.
Sebastian Festner, Jasta 11, who claimed Chapman's Nieuport for his 11. victory.
60. Sqdn. RFC lost another three Nieuports in this fight to
LvR, MvR and
Kurt Wolff.
