It had twin spring columns under the gun, on either side of the buffer. They occupied less vertical space than a single column, allowing the gun to be kept lower down on the axletree. The carriage had no axletree seats, since the limber could carry three gunners.The shield was made of hardened Nickel steel and was designed to withstand the bullets of the Romanian rifle even at close range. It was composed by two parts and had four little windows for convenience of laying. The lower shield was in two separate portions, the upper part fixed, while the lower one mobile. Unlike the Krupp shields it had not folding top.The gun was equipped with collimateur with aiming circle and a spirit level mounted on a special support. The sight was graduated up to 6000 m. It was not fitted for an independent line of sight, but the panorama sight was adopted before the outbreak of the Balkan War. It had also a mechanical fuze setter.An armoured observatory weighting 27 kg was carried on one of the ammunition wagons. It could fire both Schneider and Krupp shells, while the Brisanzschrapnell Ehrhardt (Rheinmetall) was introduced in 1912.The data came from Таблица за стрелба на 75 м/м полско скорострелно оръдие образец 1904 год. Sofia : Печатница Воененъ Журналъ 1906.Effect of the fire of a four guns quick-firing battery
