At the beginning of the show Cheyenne looses his gun. The next day he rides back to the location where he lost it but a gun is in his holster. It is plainly seen as he gets off his horse. Inside the barn his holster is empty again. Later he has to borrow a gun in town.
Cheyenne's horse comes up lame with left front hoof. Tad works on the horse later on but tries to patch up the right one.
