Totally agree with you. And there is an actor who looks so much like McAufull it's scary. He's the character in the movie "Lonesome Dove." He is the leader of the gang that gets Jake to ride with them. Then, they kill two farmers, hang their dead bodies and burn them as they dangled from a rope.
Gavan O’Herlihy is the Lonesome Dove actor of whom you speak, and I agree he did look like Terry M.
