Todd:  Welcome to the KCA Forum!  Your Family Heirloom Krag, #445630, was probably assembled around April, 1903.

  The closest numbers in Frank Mallory's "The Krag Rifle Story", 2nd. edition, Appendix list, are #445615 (1898 Rifle - documented 01/22/1907 in Frankford Arsenal ammo test) and #446062 (1898 Rifle - recorded 04/08/1910 on USS Kansas - "blew up").

Only a very small percentage of actual Krag serial numbers have been recorded and found in researched documents.
