Civil War Allen & Wheelock Second Type Sidehammer Revolver, serial number 546, caliber .32 rimfire with a six shot cylinder and a 4″ long octagonal barrel. These revolvers were made between 1859 and 1862 and were a popular private purchase secondary weapon for both Union officers and enlisted men. This example has matching numbers and is in very good working condition. All of the metal has a light gray patina with only minor faint pitting. The walnut grips show minor handling marks and retain a good deal of original finish. As an antique gun this will transfer without any restrictions.
