A complicated built-up design used on early French Battleships. After those ships were scrapped, the guns were then used as coastal artillery during World War II.
I have not been able to determine the differences in the Model years, but I suspect that it had to do with the mountings. Actual bore length was 48.92 calibers.
Some of the APC shells for these guns were converted to aircraft AP bombs.
