Serial No. 509970, manufactured early 1891, chambered in .45-70 Government, featuring a 32 ½” round barrel. This rifle presents with a classic dark plum patina, complemented by scattered traces of original blue in protected areas. Factory markings on the barrel, breechblock, and lock plate remain clear and well-defined. The stock shows expected handling wear, with some wood loss along the right edge measuring approximately 3½ inches. A handsome 1891-dated cartouche is sharply visible on the right flat. The comb is marked “9/B/37,” indicating a likely unit and rack number, offering insight into its service life. Mechanically, the action is tight and functions correctly, and the rifle retains its distinctive integral ramrod bayonet. As the final variant of the Springfield Trapdoor series.
