The Battlrship Courbet (1925-1926)
Here is Courbet as he appeared in 1925-1926 post WWI prior to the refits of 1933 and 1939.
Notice that a tripod foremast has been added, and most notably, a more robust platform structure on multiple levels installed with a cruiser type fire control director/rangefinder added atop the mast-house, as well as a director atop the conning tower. Rangefinders have been added abreast of the tripod mast. Also, the main mast has been truncated.
