Slow firing jacket field gun (Mantelrohr), cylindro-prismatic wedge breech mechanism with an expanding steel obturation ring. Two wooden wedges, weighting 300 kg each, were placed behind the wheels to counter-recoil. The Turkish Army captured some of these guns during the war against Greece in 1896 and used them to strengthen the defence of the Odrin fortress. In 1916 the Bulgarian Army captured at least two of these guns.
