Question: What was the name of the Italian bolt-action, magazine-fed, repeating military rifle that Lee Harvey Oswald used to assassinate U.S. President John F. Kennedy?

<P0-S0> 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. <P0-S1>  He also purchased a revolver from a different company, by the same method. <P0-S2>  The Hidell alias was determined from multiple sources to be Oswald. <P0-S3>  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. <P0-S4>  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. <P0-S5>  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. <SEP> <P1-S0> The President's Commission on the Assassination of President Kennedy, known unofficially as the Warren Commission, was established by President Lyndon B. Johnson through Executive Order on November 29, 1963 to investigate the assassination of United States President John F. Kennedy that had taken place on November 22, 1963. <P1-S1>  The U.S. Congress passed Senate Joint Resolution 137 authorizing the Presidential appointed Commission to report on the assassination of President John F. Kennedy, mandating the attendance and testimony of witnesses and the production of evidence. <P1-S2>  Its 888-page final report was presented to President Johnson on September 24, 1964 and made public three days later. <P1-S3>  It concluded that President Kennedy was assassinated by Lee Harvey Oswald and that Oswald acted entirely alone. <P1-S4>  It also concluded that Jack Ruby also acted alone when he killed Oswald two days later. <P1-S5>  The Commission's findings have proven controversial and have been both challenged and supported by later studies. <SEP> <P2-S0> Carcano is the frequently used name for a series of Italian bolt-action, magazine-fed, repeating military rifles and carbines. Introduced in 1891, this rifle was chambered for the rimless 6.5×52mm Carcano cartridge ("Cartuccia Modello 1895"). <P2-S1>  It was developed by the chief technician Salvatore Carcano at the Turin Army Arsenal in 1890 and called the Modello (model) 91 or simply M91. <P2-S2>  Successively replacing the previous Vetterli-Vitali rifles and carbines in 10.35×47mmR, it was produced from 1892 to 1945. <P2-S3>  The M91 was used in both rifle ("fucile") and shorter-barreled carbine ("moschetto") form by most Italian troops during the First World War and by Italian and some German forces during the Second World War. <P2-S4>  The rifle was also used during the Winter War by Finland, and again by regular and irregular forces in Syria, Libya, Tunisia, and Algeria during various postwar conflicts in those countries. <SEP> <P3-S0> 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. <P3-S1>  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.
