U.S.I.D. marked Remington-Keene bolt-action Frontier Model rifle in 45-70 cal. 24” barrel, blue finish, wood stock with a very faint inspector’s cartouche on the left side of the stock at the wrist; #U.S.I.D. 213 stamped on the left side of the receiver along with “H.N.” inspector stamps on the breech end of the frame and breech end of the barrel (left side) along with “W.W.K.” and “P” proof on the top of the receiver along with an arrow facing the rear sight. This gun is in overall very good condition showing a fair amount of original blue mixed with a plum colored patina on metal surfaces. Fine shiny bore. Crisp action. Good markings. Original sights. Wooden stock has some scattered mars and scratches from carry and storage use and an old age crack on the right side. Original sling swivels.
