The 6.5 mm Carcano rifle owned by Lee Harvey Oswald
In March 1963, Lee Harvey Oswald, alias "A. Hidell", purchased a 6.5 mm Carcano rifle (also improperly called Mannlicher-Carcano) by mail order. He also purchased a revolver by the same method. It is officially accepted that this was the rifle that was used in 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.
