The 12mm Galand was designed and patented in by Charles-François Galand (1832–1900), a French gunsmith in 1868 as opposed to the 12mm Perrin that was designed in 1859. The rim thickness of the Galand differs from the Perrin and the two are not interchangeable. (See also Erlmeier, Brandt Ref. 175, the Perrin and Galand are both classified under the French Thick rim cartridge).
