[Fistful of dollars] Can a metal chest plate really protect you from the guns of the wild west? What is the minimum thickness required to not gain a few new bellybuttons in a gunfight?

The case of Ned Kelly in Australia says that you can armor up against mid/late 1800s firearms. Hell, Civil War officers wore half-cuirasses.

The part where it gets unlikely is not that the plating works, but that the shot *only* hits the plating. This is where they finally got Kelly, too- he didn't armor his *legs*.
