I too enjoyed a lot of his work. One of his last TV efforts was as “Hec Ramsey” where he combined Paladin with a bit of Sherlock Holmes in the early 1900s Indian Territory (Oklahoma). I believe that the time slot was split between several shows so I kept missing these episodes as I had no interest in the other revolving programs.
He played a veteran lawman who was a good man with a gun but now was not afraid to use modern (1900s) science to solve crimes. His foil was the new, college-educated Police Chief (Rick Lenz) who had strong doubts based upon prior reputation. Also starred Harry Morgan as town doctor (prior to his Col.Potter role on M*A*S*H). Very well done in an honest effort to show the American West evolving into the modern civilization.
Yes, Hec Ramsey was an excellent series.
