Right after Denton drinks from the broken liquor bottle at the beginning of the story, he's shown with a large scratch on the right side of his face. In the next scene with Liz, the scratch is gone.
When Hotaling Breaks The Bottle It Is Opaque. When Denton Picks It Up It's Transparent.
When the bully, Hotaling, throws Denton into the street and follows him out with a liquor bottle in his right hand, the bottle is corked. In the next cut, Hotaling is shown pouring liquor onto Denton's face. However, Hotaling is never shown removing the cork, and the cork is nowhere to be seen - not in the bottle, not in Hotaling's left hand, and not on the ground.
At the beginning of the episode, the bully breaks a bottle and throws in on the ground in front of the saloon, where much of it spills before Mr. Denton picks it up to drink the rest. At the very end of the episode, supposedly late the next night, the final camera shot from above as Fate rides out of town, you can still see the dark, wet dirt from the spilled drink in front of the saloon.

TV antennas can be spotted in the distance.
Al Denton is shown singing the song "How Dry I Am," in order to get a drink from Dan Hotaling. However, what we know as "How Dry I Am" was part of Irving Berlin's "The Near Future" which was written in 1919. This episode takes place before the turn of the 20th Century.
In the opening shot of the wagon coming into town, oil derricks can be seen above the town buildings on the left. Also, in the distance is a graded dirt road, and modern structures atop the hills.
The potion bottle that Denton drinks from, although corked, is threaded along the top edge. Obviously not a bottle from that era.
