This is a pedestal-mounted deck gun employing bag ammunition. It is commonly found in shore emplacements for coastal defense and limited antiaircraft use. Strongly resembling the type 3d year 12-cm/45 gun in design, this weapon also has three recoil cylinders all mounted above the tube and an interrupted thread breech block hinged on the right. This gun has been found both with a splinter shield attached, and without.
