Diary for Monday, April 19, 1915:
Western Front: Morane ‘L’ fighter (Lt Roland Garros) , damaged by German rifleman Schlenstedt in Courtrai rail station, makes forced landing behind German lines, near Ingelmunster. Attempts to burn plane fail to prevent SECRET MG BULLET DEFLECTOR DEVICE FALLING INTO GERMAN HANDS. Garros tells captors he has shot down 5 aircraft since April 1.
Germany: The captured armored airscrew from Garros fighter plane is sent post-haste to Döberitz, Berlin. Feldflugchef Thomsen orders it to be copied, but a first attempt (by Brunnhuber) fails. Anthony Fokker is sent for. Within 6 days, at his Schwerin works, Fokker’s engineers, Luebbe, Heber and Leimberger, devise a MECHANICAL INTERRUPTER GEAR to fire the MG only when propeller blades are clear of its line of sight. This Fokker device (for which Anthony Fokker claims sole credit) differs entirely from the captured device and is actually based on a system patented by German engineer Franz Schneider (from June 15, 1913).
At Döberitz, a Fokker M 5K (EI/15) monoplane is fitted with the Parabellum gun, Fokker interrupter gear and adjustable head-rest and successfully demonstrated. Fokker EI single-seat fighters, armed with 7.92 mm LMG 08 MGs are ordered from Fokker.
