Remarks :

Mechanical machine gun (mitrailleur) introduced in the Russian Army in 1871 and manufactured by the firm Ludwig Nobel of Sankt Petersburg. It was based on a 12.7mm six barrels Gatlin machine gun bought in 1862, and on a 10.7mm ten barrels machine gun designed by col. Aleksandr Pavlovich Gorlov, a member of the Russian Artillery Committee. In the machine guns delivered to the Bulgarian Army the barrels were mounted on the carriage of the 4 pdr field gun with an improved iron frame. They fired the same ammunition as the Berdan 2 rifle. At the beginning of the Russo-Turkish War 16 ten and six barrels machine guns were delivered to the Bulgarian National Army. At the beginning of the Balkan War 8 ten barrels machine guns were still in service.
