The original 7.5x57mm French cartridge was adopted in 1924, and slightly modified to 7.5x54mm in 1929 to avoid confusion with the German 7.92x57mm round. It was retained by the French military into the 1970s due to a stubborn refusal to match NATO standards, accompanied by their temporary withdrawal from the alliance in the late ‘60s and early ‘70s. It was replaced by NATO standards after that.
I love the looks.
