Talk:12.5inch Twin Secondary Gun Mount/@comment-3284624-20161220175040

As a historical note, the only 12.5-inch guns used by warships were the RML 12.5-inch muzzle leaders on 1870s and 1880s British pre-dreadnoughts as the main guns, and the mains used on rebuilt Andrea Dorea-class and Conti di Cavour-class Italian dreadnoughts.
