 DATE: The movie begins in 1868; however, all of the guns used are  mid 1870s vintage. The pistols used are Colt 1873 Peacemakers and  the rifles are Winchester Model 1892. Although both Spencer and  Volcanic Repeating Arms both produced cartridge firing repeating  rifles, it is more likely that most of the men, not being  professional gun hands, would have carried Civil War surplus rifles  (muzzleloaders)like Mose.
