Reportedly approximately 700 Spiller & Burr percussion revolvers were manufactured in Atlanta, Georgia, circa 1862-1864, and another roughly 700 were manufactured at the Macon Armory after the firm was purchased by the Confederacy in January of 1864. Production started with a very optimistic government contract of about 15,000 revolvers in 1862 but was stopped in November 1864 due to Sherman's March to the Sea. The revolver is patterned after the Whitney Navy Model and has a distinctive solid brass frame with "C.S." stamped on the left side. This Second Type features a large cone front sight, frame groove rear sight, six-shot cylinder with safety notches between the nipples like the Remington revolvers, and smooth walnut grips. The barrel, loading lever, cylinder, trigger guard, frame under the trigger guard, and the butt are all marked with the matching serial number.
