A stupid question if I may. Where would you find a number like the one you quoted, M954? I see a Mod. 1908 on the right side of the front of the action, a four digit serial # and on the crest, 15 de Novembro de 1889.slug said:Nobody has specified exactly what model it is.
If it is an M954 then it would be.30/'06.
