Lyle Swann goes back in time to November 5th, 1877. The same "time travel arrival date" was used in Back to the Future (1985) (November 5th, 1955) and Time After Time (1979) (November 5th, 1979).
It's yet to have a full uncut version released on DVD or even Blu-Ray. Every release has something cut or missing.
The name of the protagonist, Lyle Swann, comes from "I'll swan," an old English term, heard much in the American southwest, meaning "I'll swear and warrant," used primarily as a mild epithet of surprise.
When Swann goes back in time to 1877 he tangles with outlaws Porter Reese and the Dorsett Brothers. Though not stated in the film, Reese and the Dorsetts were probably Confederate Civil War Veterans. Reese makes the statement about Swann's motorcycle ".. if General Lee had that machine, we'd of won the war." Reese makes another statement denoting a soldier's background when he gets to San Marcos and at gunpoint says to the village priest, Quinn, ".. that I can't have my men being shot."
The first scene of Swann in the Old West shows him riding as a brilliant sun oranges up the sky. Symbolically this welcomes the audience to 1877 (19th century) just like the orange or yellowish tint found in Old West and Victorian photos, daguerreotypes and still portraiture.
