Remarks :

Quick firing field gun, recoil system with hydraulic buffer and springs, swinging block breech mechanism, traverse on pivot. It was equipped with panorama telescopic sight, and fitted for an independent line of sight. According to Bulgarian sources, Germany supplied only 8,864 shells for these guns, but they can fire all kinds of Krupp ammunition employed by the Bulgarian artillery during the World War. Moreover since the Bulgarian shell was heavier, it is probable that the muzzle velocity decreased, being like that of the common Krupp guns (500 m/s instead of 510 m/s) and simplifying the work of the Bulgarian gunners.
