Dial Duwayne Ryder (June 12, 1938 – October 20, 2011) was an American gunsmith, who gave evidence to the investigation of the death of President John F. Kennedy.
Ryder worked at the Irving, Texas Sports Shop and stated that he possessed a record of Lee Harvey Oswald's name.
Ryder showed agents of the Federal Bureau of Investigation, on November 25, 1963, a tag which he claimed was in Oswald's handwriting.
[1] Dial told author Leo Sauvage the rifle Oswald ordered from Chicago, Illinois came equipped with a telescopic sight.
[3] Ryder believed that a close inspection of the 6.5 mm Mannlicher Carcano owned by Oswald would reveal that neither he or his shop worked on the gun.
