The 203mm/55 Modèle 1931 gun was a medium naval gun of the French Navy.These guns used the same ammunition as the 203mm/50 Modèle 1924 gun and were very similar except for the longer bore. It is believed that the guns were built from tubes of the older 240mm/50 Modèle 1902 guns.[1]
Although commonly described as being used as the main battery of the heavy cruiser Algérie, mounted in four twin turrets,[1] Algérie in fact used the same 203mm/50 Modèle 1924 as the rest of the French heavy cruisers.[2]
In fact as written in French Cruisers 1922 - 1956 these guns did not exist.[3][4]
