Goofs

When trying to escape Kuroda by running (then falling and tumbling) down the steep embankment, Link loses his bedroll. At the bottom of the cliff, it reappears in his hand, and he loses his grip on it as he rolls over the final time. The bedroll lands next to him.

(at around 55 mins) When Pepita is closing the brothel for the night, she goes to a switch by the bar and turns a rheostat switch to dim the electric chandelier. Electric lighting did not become common until the early 20th century and rheostat dimming switches were not invented until the latter part of the century.

That said, it is not an "electric chandelier", and the "rheostat" is actually a gas cock. Pepita is decreasing the gas flow to the chandelier, thus dimming the lights. Gas lighting was developed at the end of the 18th century.

When Kuroda throws the knife into the door frame the shot is shown in reverse , the string that pulls the knife can be seen.

As Kuroda searches for Stuart on horseback after Stuart attempts to get away from him by firing his revolver near Kuroda's horse, in several locations one can see numerous modern tire tracks on the ground.

In the opening scene, Link takes his saddle off his horse and shoes the horse away, leaving the bridle on his horse. Letting the horse go free, with a bridle still on the horse, is a very wrong thing to do. Not having a rider, the horse in running free, might catch the bridle on a tree or on a rock. Then the horse would have no way to free itself. Link should have taken the bridle off the horse, as well as his saddle.

At the end, when Link Stuart is waiting for the train, he looks at the train coming around the bend. Behind the train, a car can be seen driving along a road near the tracks.

This story takes place around 1870. During the train robbery, several cavalry soldiers are shown with foreign-type bolt-action rifles. The US cavalry troops were not issued bolt-action rifles during this period; they were equipped with either lever-action Spencer carbines or single-shot Sharps carbines. The single-shot "trap-door" Springfield carbines were introduced in 1873. Other anachronistic weapons used in the film are: Colt Single Action Army pistols (1873), Winchester Model 1894 lever action rifles (1894) and the soldiers and Indians had Mannlicher Carcano M91 bolt-action rifles (1891).

Film takes place in 1870 in rural western US, yet electric power lines appear over the streets in rural western America until the 1920s & 1930s. Mace & his 3 companions ride into town at 1:03:12 in the film, as power transmission lines are shown over the street.

Link leaves the sword hanging from a power line. However, no power lines existed in 1870, when the film takes place. Power lines were not installed in such rural areas until the 1920s & 1930s.

Despite being set in the Western United States, the trains use British/European style buffer and chain couplings instead of the link and pin or Janney couplings used in the US.
