This is a Model 1884 Trapdoor Springfield .45-70 caliber Standing Rock Reservation carbine. The Standing Rock Reservation is in North Dakota and South Dakota in the United States. The sixth-largest Native American reservation in land area in the US, Standing Rock includes all of Sioux County, North Dakota and all of Corson County, South Dakota. The reservation has a land area twice the size of Delaware and has a population of 8,217 as of the 2010 census. There are 15,568 enrolled members of the tribe. The largest communities on the reservation are Fort Yates, Cannon Ball, and McLaughlin. Together with the Hunkpapa and Sihasapa bands, the Standing Rock Sioux Tribe is part of what was known as the Great Sioux Nation. The Black Hills, considered by the Sioux to be sacred land, are located in the center of the territory awarded to the tribe. In 1874, in direct violation of the treaty, General George A. Custer and his 7th Cavalry entered the Black Hills and discovered gold, starting a gold rush. The United States government wanted to buy or rent the Black Hills from the Lakota people, but led by their spiritual leader Sitting Bull, they refused to sell or rent their lands. The Great Sioux War of 1876 was a series of battles and negotiations that occurred between 1876 and 1877, with the Lakota Sioux and Northern Cheyenne warring against the United States. Among the many battles and skirmishes of the war was the Battle of the Little Bighorn, often known as Custer's Last Stand, the most storied of the many encounters between the U.S. army and mounted Plains Native Americans. It was an overwhelming Native American victory. This carbine has the correct “U.S. MODEL 1884” marked breech block. The lock plate shows a clear “U.S. Springfield” with eagle motif. The carbine walnut stock is in unusually beautiful condition that shows only the most minor of handling marks and has been modified from its original rifle length. The firearm shows all correct “VP” over “eagle head” barrel proof marks, and it even retains good aged blue on the trigger guard. The firearm has been stamped with a Standing Rock Indian Agency cartouche on the left side of the stock. The trapdoor has also been adorned with square shank brass tacks, further confirming its time spent at the Standing Rock reservation. This is a standard model firearm that was used in every major engagement from the Battle of the Rosebud and Battle of the Little Bighorn to Wounded Knee. Serial Number: 347825. This firearm qualifies as an antique and does not require FFL Transfer or NICS Background Check.
