Remarks :

Slow firing jacket field gun (Mantelrohr), cylindro-prismatic wedge breech mechanism with an expanding steel obturation ring, traverse on pivot. It was fitted with a direct fire sight and aiming circle. It was modernised to use smokeless powder, but the rapidity of fire was not very great. In 1885-86 Turkey bought from Krupp 793 of these guns.
