'304531' - There is no listing for Krag #304531 in The Springfield Research Services (SRS) data.

Most Krag serial numbers do not appear in the SRS research, since only a minority of rifles and carbines were recorded in surviving and researched records.

Your Krag receiver was likely manufactured and assembled into a finished arm in approximately December, 1900 to January, 1901. An acceptance cartouche, dated 1901, would be likely.

If you post close and detailed pictures of various areas of your Krag, you will get useful information and suggestions.
