That serial number is not listed in the SRS records, but is inside the range that M1898 carbines have been recorded. We would need close up pictures of the the rear sight, front sight, cartouche, handguard, and stock in front of the handguard in order to have an opinion as to whether the carbine is one of the "real" ones. The 1899 stamped on the stock would lead me to think it is a cut down rifle since a real M1898 carbine would have a 1898 cartouche.
