Context_1 : The .45-75 Winchester "Centennial" is a centerfire rifle cartridge developed in 1876 for the newly designed Winchester Model 1876 "Centennial" lever-action rifle. Winchester Repeating Arms Company introduced the new rifle and cartridge at the United States Centennial Exposition. The Model 1876 rifle used an enlarged version of the famous Winchester Model 1873 action to offer a lever-action repeating rifle using cartridges suitable for big-game hunting. The cartridge and rifle enjoyed brief popularity with Gilded Age American hunters including Theodore Roosevelt, and was issued to the Canadian North-West Mounted Police and to Texas Rangers. Context_2 : Ruth Hyde Paine (born September 3, 1932) was a friend of Marina Oswald, who was living with her at the time of the JFK assassination. According to five government investigations, Lee Harvey Oswald stored the 6.5 mm caliber Carcano rifle that he used to assassinate U.S. President John F. Kennedy in Ruth Paine's garage, unbeknownst to her and her husband, Michael Paine. Context_3 : The Howa Type 89 Assault Rifle (89式小銃 , howa-hachi-kyū-shiki-syōjū ) , referred to as the "type 89 5.56mm rifle" (89式5.56mm小銃 , hachi-kyū-shiki-go-ten-go-roku-miri-syōjū ) , is a Japanese assault rifle used by the Japan Self-Defense Forces, the Japan Coast Guard's Special Security Team units, and the Special Assault Team. It was never exported outside Japan due to its strict anti-hardware export policy. It is known in JGSDF service as Buddy. Context_4 : The Solothurn S-18/100 20 mm anti-tank cannon was a German and Swiss anti-tank rifle used during the Second World War. It had a semi-automatic action in a bullpup configuration. As a result of its large, powerful ammunition, the gun had a tremendous recoil, and its size made portability difficult. The feed was either from a five or (more usually) ten-round magazine that was attached horizontally to the left side of the gun. The gun used 20×105mm belted-case ammunition which it shared with the S 18-350 aircraft cannon that was developed from the rifle. A Finnish source gives armour penetration of the gun (probably achieved with the Hungarian APHE-T round, since it was the only type used in Finland) as 20mm at a 60-degree angle at 100-metre distance, decreasing to 16mm at 500 metres. Context_5 : The Type 97 20-mm antitank rifle is a Japanese semi-automatic anti-tank rifle used before and during the Second World War. Adequate for the early part of its deployment, it was rendered obsolete by advancement in tank armor. Context_6 : The Type 99 sniper rifle (九九式狙撃銃 , Kyūkyū-shiki sogeki-jū ) was a Japanese sniper rifle used during the Second World War. It was a sniper version of the Type 99 rifle, chambered in the 7.7×58mm round. There were a few variations of the Type 99 sniper rifle, some with the straight bolt and the scope mounted on the left side of the receiver which allowed use of stripper clips. Another variation was one with a bent bolt and the scope above the receiver which required the sniper to load the rounds one at a time. The shorter barrel, combined with the larger caliber round made concealment more difficult than the Type 97 rifle that preceded it, considering the louder muzzle blast and flash caused by the increased powder capacity. Context_7 : John H. Blake of New York constructed his rifle in response to the fact that very few domestic designs were submitted to US Army rifle trials (1890–93). The rifle used a unique, 7-round rotary magazine. It was unique because it was detachable, whereas other rifles at the time using similar type of feed used non-detachable rotary magazines (Savage M1892). As such the detachable magazine was often described as a packet, or en-bloc clip, due to the lack of a more proper term at the time. Context_8 : The Ruth Paine Home at 2515 W. 5th Street in Irving, Texas, United States, is the location where Lee Harvey Oswald spent the night before assassinating President John F. Kennedy on November 22, 1963. It was from the house's garage that he removed the rifle he used for the assassination, which he had previously concealed there. Context_9 : The Howa Type 64 Battle Rifle (64式自動小銃 , Roku-yon-shiki-jidou-shoujuu ) , is a Japanese battle rifle used exclusively by the Japan Self-Defense Forces and the Japanese Coast Guard. It is a gas-operated, selective fire weapon which is chambered for the 7.62×51mm NATO round and uses a detachable 20-round box magazine. The Type 64 was never exported due to Japan's strict anti-hardware export laws. It has been superseded by the more advanced Howa Type 89 from 1989 to 1990, but is still in service with all branches of the Self-Defense Forces and the Japanese Coast Guard. Context_10 : In March 1963, Lee Harvey Oswald, using the alias "A. Hidell," purchased by mail order a 6.5×52mm Carcano Model 91/38 infantry rifle (described by the President's Commission on the Assassination of President Kennedy as a "Mannlicher–Carcano" ) rifle with a telescopic sight. He also purchased a revolver from a different company, by the same method. The Hidell alias was determined from multiple sources to be Oswald. It is officially accepted that the rifle was fired by Oswald from the Texas School Book Depository in Dallas, Texas, to assassinate United States President John F. Kennedy as his motorcade drove by on November 22, 1963. Photographs of Oswald holding the rifle, a palmprint found upon examination of the rifle, and detective work tracing its sale, all eventually led to Oswald. Marina Oswald later testified she was told by Lee that the rifle was also used before in an attempt to assassinate retired U.S. Army General Edwin Walker in Dallas. fact_1 : The Ruth Paine Home at 2515 W. 5th Street in Irving, Texas, United States, is the location where Lee Harvey Oswald spent the night before assassinating President John F. Kennedy on November 22, 1963. fact_2 : In March 1963, Lee Harvey Oswald, using the alias "A.
