Continuity: Harker confiscates firearms from five Devil's Hole members who are playing poker in the saloon. The sixth member is down in the tunnel, and didn't turn over his gun. Yet when the outlaws go to collect their weapons, six are given back their side-arms.

Continuity: Heyes and Curry ride out of town wearing shirts and vests. Both turn to look behind them when they hear the posse coming. As they spur their horses into a gallop, they're suddenly wearing heavy coats.

Revealing: The electric light bulb in Lom Trevors' lamp is visible. In one shot, you can even see the filament wires.

Continuity: When Miss Porter enters the office, the coffee mug on Lom's desk jumps from the blotter onto the wood surface between shots, even though no one touches it. It also reverses its orientation: the handle switches from pointing left to pointing right.

Continuity: When Harker rouses a sleepy Heyes and drags him to the saloon, Heyes' hair is falling over his forehead. The shot cuts, and his hair is combed back. Then he steps through the curtain to talk to Wheat, and the hair is over his forehead again.

Continuity: The Devil's Hole Gang is referred to as "seven sorry lives of crime." But there are only six of them.

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.

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.

Continuity: In the saloon, Heyes and Curry are standing at the bar about four feet apart. After the deputy sheriff kicks the orchestron (a 19th C. jukebox), the camera angle reverses - and Heyes and Curry are suddenly shoulder-to-shoulder at the bar.

Continuity: Deputy Harker keeps checking his pocket watch while making his rounds. The first two times he looks at it, the watch face has Roman numerals. On his third check, it has regular numbers instead. The fourth time, the Roman numerals are back again.

Continuity: Heyes and Curry walk into the saloon covered with trail dust from head to toe. But when they leave, Heyes' hat is spotless.

Visible crew/equipment: When Heyes and Curry leave the saloon and walk across the street, a microphone mounted on the camera rigging pops up into the shot at the bottom of the frame and follows along beside them. (This is visible in the US aired and vhs versions, but was edited out of both the BBC version and the recent dvd release.)

Continuity: In his showdown match with McCreedy, Heyes deals out five cards in each row on the table. But in the next shot, there are six cards in each row.

Continuity: While he's working to open the safe, Heyes is wearing his coat. Then he isn't. Then he is again.

Plot hole: Early in the episode, the sheriff starts going through his pile of wanted posters. According to the story line, 18 days then pass. At the end, the sheriff, standing in the exact same position and wearing the same clothes, is just finishing his search through the posters.

Revealing: At Armandariz's hacienda, a power cord is peeking out from behind the large chest against the wall in the main room.

Continuity: While Heyes and Curry are guarding the gold shipment, Heyes' hat keeps changing positions on his head between takes. First it's down over his hairline, then it's pushed back, etc.

Continuity: Heyes and Curry enter the train depot at 8 pm. It's dark outside. When they come back to the platform, it's daylight. When the train leaves, it's dark again. Midway through its 60-mile journey, there's another shot of the train in daylight, followed again by more night shots.

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.

Continuity: When the bad guys rough up Heyes, his hair is disarrayed. But when the shot cuts, it's neatly combed again.
