Have Gun â Will Travel was a popular American Western television series that aired between November 23, 1958, and November 22, 1960. There were 106 episode broadcasts on CBS. It was the only significant radio show that originated on television, many of the episodes having been adapted from television programs broadcast earlier, though some were original to radio, and it was also one of the last radio dramas featuring continuing characters. John Dehner played Paladin and Ben Wright usually (but not always) played Hey Boy.
