Remarks :

Turkish mountain gun captured in 1877-78. During the War against Russia, the Turkish mountain artillery is reported to be equipped with 5.5 cm bronze and steel breech-loader guns mounted on steel carriages. The Turkish gun may be identified with a Krupp 6 cm mountain gun exhibited at the Vienna International Exposition in 1873, equipped with the Broadwell breech mechanism.
