Remarks :

Quick firing field gun, with recoil system with hydraulic buffer and springs, single-motion wedge breech mechanism, traverse on pivot. The carriage had no axletree seats, since the limber could carry three gunners. It was equipped with the “Ghenea” pedestal sight, used for direct and indirect laying. It was not fitted for an independent line of sight. An observation ladder weighting 25 kg was carried on one of the ammunition wagons. In 1912 the Brisanzschrapnell Ehrhardt (Rheinmetall) was introduced.

Romania bought 360 guns M. 1903 (90 batteries) and 240 guns M. 1907/12 (60 batteries). There are only little differences between the two models of the gun.
