It was almost identical to the gun adopted by the Prussian Army, except that the latter had a double wedge breech mechanism with copper obturation. In 1864-74 Turkey bought from Krupp 653 of these guns, some of them were captured by the Russians in 1877-78 and later delivered to the Bulgarian Army. Also the Romanian Army adopted this gun, buying 96 pieces in 1868. The two models were alike, but the carriage of the Romanian gun was made of elm or oak wood, while the carriage of the Turkish gun was metallic. Romanian modelTurkish model
