U.S. model 1899 Krag carbine, #357169 (?), would have been assembled at Springfield Armory around November, 1901.

Your Krag carbine was altered by someone to use it for Hunting - (ventilated rubber butt-pad, dove-tailed sporting rear-sight, and improvised sling & swivels).

Your photos don't show Stock or front-sight well enough to tell if they are original carbine parts.

Model 1899 Krags were only built as carbines.

Welcome to the KCA Forum. Nice family heirloom!
