This is the last unique revolver for the moment, the Shielded Papperbox.
The concept was introduced in the 15th century, but this type of handgun become popular in North America from 1830 until the American Civil War.
Pepperboxes should not be confused with a volley gun, a firearm that fires multiple projectiles simultaneously. The difference is, that the pepperbox, is a repeater firearm.
Friday we gonna start showing the rifles of sunset rangers, stay tuned!
