Steyr Mannlicher-Schonauer 1903

This is the Mannlicher-Schonauer 1903 This rifle dates to 1903 when the 6.5x54mm cartridge and both military and civilian rifles to shoot it were introduced. Austria and Greece adopted the 1903 military rifle and the 6.5x54 cartridge that same year. The 1903 Mannlicher rifles and carbines were the last designs of Ferdinand Ritter Von Mannlicher, who died the next year, and his friend Otto Schönauer who designed the exceptional rotary drum magazine intrinsic to all Mannlicher-Schoenauer rifles. Mannlicher-Schoenauer rifles and carbines were exclusively manufactured at Oesterreich Waffenfabrik Gesellschaft Steyr in Steyr, Austria. Steyr made carbines and sporters after World War One in various calibers.
