You tell me. Is that a Nylon brush in that hand? The movie this comes from was set in 1865. I know... I know. Endless loops of gaffs and goofs. No. Not looking for trouble.
Those are Clint's hands. The Good, the Bad, and the Ugly. I thought the production was better than to succumb to a prop error like that. Or... was there a brush like that back then? Can anyone restore my faith in Sergio Leone or did he just toss Mr. Eastwood that cleaning brush out of his personal gun cleaning kit because it just looked better in the scene?
