The U.S. Model 1873 Springfield trapdoor rifle was the first of the U.S. 45 Government center fire caliber (45-70) arms. This early Model 1873, serial number 24,355, was made in 1874. It was later updated with a replacement stock, barrel, and 1884 rear band. The 32 5/8"" round barrel has a fine bore with strong rifling. The barrel has a V over P over eagle at the breech. It has an even brown patina with light peppering. The Model 1873 rear sight is attached with later slotted screws. The early breech block is marked MODEL over 1873 over an eagle over crossed arrows over US. It has traces of its faded case colors. The early lock plate is marked U.S. over SPRINGFIELD over 1873 with an eagle to the rear of this marking. All the metal parts have an even brown patina. The swivels and ramrod are present and it is equipped with an after market sling. The stock is very good with no cracks or chips, light to moderate issue dents and dings, and no evidence of a cartouche. The three-click action functions correctly. If you need a pre-Custer trapdoor, this gun can fill that hole in your collection.
