The Man Who Broke the Bank at Red Gap - S2-E17
Factual error: An egotistical, prissy and dishonest lawyer like Mr. Fletcher wouldn't make the mistake of allowing his name to be misspelled on his office door. It reads "Winfred Fletcher." His first name, as it's pronounced throughout the episode, is "Winford." (00:26:50)
Dreadful Sorry, Clementine - S2-E10
Factual error: Heyes burns the photo - but he shouldn't have been able to. In the 1880s, it should be printed on tin and not on paper. (00:11:00)
Alias Smith and Jones (90 min.) - S1-E1
Factual error: Kyle strikes a match on the wooden floor to light the dynamite's fuse. In the early 1880s (the era in which this series is set), a portable flint-and-tinder kit was the common method of sparking a light. While "strike anywhere" matches had been invented by this time and were quite the rage in Europe (despite an alarming tendency to explode due to the volatile chemicals used), they were an unknown commodity on the American frontier until well after the turn of the century. (00:03:00)
Alias Smith and Jones (90 min.) - S1-E1
Factual error: The telegram delivered to the sheriff's office is in an envelope with a machine-cut, transparent cellophane address window. This type of envelope wasn't manufactured until well into the 20th Century. (00:58:15)
Factual error: The sheriff and his posse raise huge dust clouds as they gallop down the road. But the stagecoach they're chasing, with four horses and four wheels, is on the same road and isn't raising any dust at all.
Wrong Train to Brimstone - S1-E4
Factual error: When the train is fully boarded, the conductor waves a lamp to signal the engineer. It's supposed to be 8 pm at night, but it's suspiciously sunny on the platform - and the signal lamp is noticeably not lit. (00:08:45)
The Posse That Wouldn't Quit - S2-E5
Factual error: Heyes gives Bridget a glowing and accurate description of Denver's Brown Palace Hotel - a landmark that wasn't built until 1892, ten years after the setting here.
The Clementine Ingredient - S3-E4
Factual error: Clem puts the paper photo into an envelope and licks the flap to seal it. Pre-cut, pre-gummed envelopes, though they'd been invented, were big-city luxuries rare-to-non-existent in the "wild" west - they were too expensive for most people (like Clem) to afford, especially in the economically depressed decades following the Civil War. You generally cut and folded your own envelopes and glued or sealing-waxed them shut. (00:33:40)
Factual error: Heyes and Curry spend months at the mine without any razors or knives. Their beards grow out - but their hair doesn't get any longer. (00:12:00)
Which Way to the OK Corral? - S2-E20
Factual error: Heyes and Curry meet Doc Holliday and Marshall Wyatt Earp in Tombstone. Wyatt, however, was never a marshall in Tombstone, though his brother Virgil was. Wyatt and Doc Holliday both left Tombstone permanently shortly after the OK Corral shootout in 1881, so wouldn't even have been there when Heyes and Curry arrived in 1883. (The year's established by Heyes reading Twain's book published in that year).
Factual error: The dresser mirror in the saloon girl's boudoir is ringed with photos - but they're 20th Century color Polaroids. (00:24:00)
The Men That Corrupted Hadleyburg - S2-E18
Factual error: Heyes plays blackjack with cash instead of chips. When he bets the limit of $1000, he pushes two small stacks of coins toward the dealer. A thousand dollars in coins would have made a substantially larger stack than this. Even if they were $20 gold pieces (which they don't appear to be) the two piles would have to be comprised of 25 coins each, which they are not. (00:30:00)
The Day They Hanged Kid Curry (90 min.) - S2-E1
Factual error: Wheat refers to the hanging of real-life outlaw Black Jack Ketchum. But Ketchum was executed in 1901. Smith & Jones is set in the 1880s. (00:27:50)
Never Trust an Honest Man - S1-E14
Factual error: For a man of the cloth, the Preacher is remarkably ignorant of one of the best-known passages of the Bible. He says that the 6th Commandment is "thou shalt not steal" and the 8th "thou shalt not kill." It's the other way around.
Don't Get Mad, Get Even - S2-E21
Factual error: A grumpy Heyes tells Georgette and Curry that he's been sleeping in a stable loft for two days without a bath or a shave. But he's completely clean-shaven: not even a hint of stubble showing. (00:15:00)
Suggested correction: He is not "completely clean-shaven." He has evident facial hair.
The Legacy of Charlie O'Rourke - S1-E15
Factual error: When Alice, Heyes and Curry dig up the gold bars, they realistically have to use both hands to lift each one. But Heyes then fills two cloth bags with six bars each, hefts the sacks easily and slings them over his saddle. Conservatively, each of those bags would weigh 180 lbs. - he's just tossed the equivalent weight of two full-grown men over his shoulder onto the horse.
Wrong Train to Brimstone - S1-E4
Factual error: This entire episode takes place in Wyoming, because of the Bannerman plot to ambush the Devil's Hole gang, but a sign at the train station where Heyes and Curry board states the elevation as 2315 feet. No location in Wyoming or northern Colorado is that low. One would have to be in California, Texas, or eastern Kansas or Nebraska. (00:04:05)
The Men That Corrupted Hadleyburg - S2-E18
Factual error: Heyes and Curry are reading the Denver Post in the beginning scene, but the Denver Post was not published under that name until 1901, nor published under its earlier name, The Evening Post, until 1893.
