After receiving a beating from Del Shamley (Richard Devon) and Bart Collins (DeForest Kelley) Jess Harper is seen with an injury to the right side of his face which has been treated with a modern band aid. Problem being it's the 1870's and band aids weren't invented until 1921 by Earle Dickson who worked for the Johnson and Johnson company at the time.
