I recall a TV episode of Gunsmoke where Festus had ridden out a good distance alone. This episode was clearly dated as being in the 1870s. In one scene Festus pulled his rifle from the saddle scabbard & it was clearly either an 1892 or 1894 Winchester, not the 1873 it should have been for the date shown.
