Crotty tells Artie to use an Ouija board to find Jim, but the Ouija board wasn't commercially introduced until 1890.
Artie uses a trick magician's cane to knock out the masseur at the bath house. such an act is impossible as the "appearing cane" is a lightweight flat metal spring that weighs barely a pound. You might be able to sting someone with it or put out an eye, but you can't knock somebody out with one.
Rusty calls the bartender "Pinocchio," but The Adventures of Pinocchio wasn't commonly read in the U.S. until 1911.
Crotty uses the word "genocide" when he welcomes the agents to his "genocide club." The word wasn't coined until the 1940s.

In the scene where Jim and Mosley are strapped to the post, Artie shows up to rescue them. Jim is released, and a fight starts. Jim jumps off the platform, punches one man, lifts his leg to kick another, and proceeds to split his pants in front. West jumps back on the platform, goes behind a post, and returns without the split.
At the end, Jim flips over the trick table, revealing a decanter, a cup full of tea, and several wine glasses. The tea in the cup is clearly a solid block when Jim flips it over (because the contents would spill), but becomes a liquid in the next shot. Also, the agents immediately lift the glasses off of the table, although they would have had to be glued down to avoid falling off when the tabletop was upside down.
Gadgets: smoke bomb, windup lockpick, exploding boot heel
During the fistfight with Klaxton, Jim's shirt is ripped on his left side. In most of the scenes it stays ripped, but when he knocks out a cowboy and steals his horse, the shirt is intact.
At the end of the episode, Cord says that Jim has killed his last two deputies. However, the only credited deputy (played by Whitey Hughes) is never accounted for. The last time he's seen is the previous night when Jim punches him unconscious.
