Continuity mistake: West's close-up before the final scene in the boxcar shows his hair to be brushed back from the right to left and his hair looks full. The next shot in the boxcar, West's hair is distinctly parted on the left and is more flat looking.

Continuity mistake: Towards the end of the first half of this show, the colonel and West are having a drink inside. Both men's clothes are spotless as they walk to the door to go outside. Once they go through the door, the colonel's jacket is noticeably dirty, especially on its right side. When West turns around from seeing Sgt. Tobin's body, the seat of West's pants is also quite dirty with a small tear in the middle of the seat of his pants. When West walks towards his horse to leave, the seat of his pants is spotless and the rip is gone.
