'Nick787' - Welcome to the KCA Forum. It sounds like you did well!

Due to the deep numerals, U.S. model 1896 Krags are often misidentified as model 1898.

Your Krag, #85723, was built around November to December, 1897, by Bill Mook's calculations and around February, 1898, in Joe Poyer's tables.

Since it was built near the date when the U.S.S. Maine sunk, it is most likely that it saw use during the Spanish War or the Philippine Insurrection.

You serial number does not appear in Springfield Research Service Data (SRS).
Its immediate neighbor, Model 1896 rifle #85722, was given back to the Government by a civilian, on 05/01/1943, during a WW II donation drive, and went to the U.S.N.
(BTW - Only a small percentage of U.S. Krags are documented by serial number in Government records).

Nice clear closeup pictures of your Krag would be enjoyed by many.
