Four-Barrel Mule Ear Custom Rifle from the 1850s

This is a custom rifle made by gunsmith P.E. Hall of Ashtabula, Ohio most likely between 1948 and 1854. It has a cluster of four .36 caliber rifles barrels (24 inches long) in an octagonal frame. The action is a quadruple set of mule ear hammers, two on each side, with a double set trigger. Pretty neat!
