actually the carcano's concentrate in austria where you had allways the same situation in the last days of ww1 1918 and ww 2 1945, a lot a captured italien rifles and soldiers with the possibilitys to bring them home or hide them in the next haystack.
the short and handy MS Model 1903 was allways the ideal alpine mountain rifle. when the german Model 1888 was the grandfather of the MS, the Model 1891 was also some kind of a greatuncle and this was making it simple to sporterise the carcano in the direction of the Model 1903.
