The French ironclad battleship Couronne (1862)

This is apparently a photograph of the French ironclad battleship Couronne, completed in 1862, after the Couronne was altered as a gunnery training ship in 1881 to 1885. The photographs is based on the Wikipedia photograph. The armour was removed and a spar deck and other additions were made to make the Couronne resemble a conventional screw two-decker. The ship was actually constructed of iron and lasted until as late as 1932, although last 22 years were as a hulk.
