At the end of the episode when Stone Calf confronts Bat Masterson and draws his knife, in the close-up the knife has an "S" crossbar typical of a Bowie knife. Afterwards in a slightly longer shot, the knife he discards is narrower with no crossbar. It appears scenes on location (with the narrower knife) are inter-cut with scenes in the studio (with the Bowie knife). The scenes on location also have a breeze blowing Stone Calf's hair. There is no breeze in the studio scenes.
