Nathaniel and his son N.G. Whitmore were gunmakers in Mansfield, Massachusetts, (located between Boston and Providence, R.I.) and manufactured a rifle presented to President Grant from citizens of Providence (in Smithsonian Museum). The younger Whitmore later worked for Sharps and Remington. The barrel has dovetailed blade and notch sights, serrated rings at the muzzle and transition point, "N. WHITMORE CAST STEEL" on the upper right flat next to the rear sight, scroll engraving at the breech, and an engraved and gold banded breech plug. It is equipped with adjustable double set triggers. The upper tang, lock, and German silver furniture are also engraved. The right side of the smooth stock has a silver patriotic spread wing bald eagle with a banner in its beak, and the left side has a large hunter star and scrollwork inlay on the cheekpiece and a silver turkey.

Very good plus with mostly gray patina on the iron, some light pitting and oxidation, aged patinas on the silver and German silver, generally crisp engraving and markings, and mild overall wear including some dings and scratches. The stock has a very discreet repair along the top edge of the forend on the right, some minor nicks and flakes at the edges, minor pressure marks and scratches, and some figure in the butt. Mechanically fine.
