Historic context :
The important technical superiority of the German artillery during the 1870 war (with the first breech-loading guns) did not prevent the General Staff from willing to improve further its material, capitalizing on the battlefield experiences.
This is how the obturation weaknesses of the old fieldguns C/61 were corrected with the design in 1873 of the C/73 guns equipped with Krupp breech blocks. Two different calibres were planned : a light 8cm (78.5mm) gun for the field artillery, manufactured in small quantities, and a heavy 9cm (88mm) fieldgun for the 'foot' artillery ('FussArtillerie').
In 1914, the obsolete '9cm K 73' ('K' = Kanone), with no recoil recuperation system, was still arming numerous units of the FussArtillerie, in a later improved version 9cm K 79 (with bronze barrel), 9cm K C73/88 (lightened tube), and mainly 9cm K C73/91 (tube in nickel-alloyed steel).
Although some still maintain some debate, all the artillery specialists agree on the fact that the numerous witnesses from French soldiers about 'dangerous austrian 88mm guns', historically unexplicable because of the absence of this country artillery of that caliber in German lines, are in fact referring to these 9cm K 73 of the FussArtillerie, placed near the first lines.
During the war, improvisations were performed to transform some of these into anti-aircraft guns, with little success. The Turkish armies used large amounts of the K73 gun, until as late as 1923.
