The "Southerner" Derringer was a neat little turn-barrel pistol. Its name, emblazoned on the top of the barrel, was obviously intended to appeal to buyers south of the Mason-Dixon line, though incongruously it was manufactured in Newburyport, Mass., by Merrimack Arms and Brown Mfg. Co. Perhaps it was the makers' attempt at letting bygones be bygones-though probably it was just a very clever marketing ploy.

Standard Southerners measured 5 inches overall and had 2 1/2-inch iron barrels, spur triggers, walnut or rosewood grips and either iron or brass frames. Some 6,500 were made between 1867 and 1869 marked on their barrels, "MERRIMACK ARMS & MANUFACTURING CO/NEWBURYPORT/MASS/PATENTED APRIL 9, 1867." Another 10,000 were turned out from 1869 to 1873 by Merrimack's successor with their barrels stamped, "BROWN MANUFACTURING CO/NEWBURYPORT, MASS/PAT APR.9, 1869."

Barrels were blued, and iron frames were either blued or case-hardened. Brass frames were silver-plated. Sometimes engraved, ivory-gripped specimens of both will be encountered. While most Southerners had square butts, there were a small number made by Brown with rounded grips and 2 1/2- or 4-inch barrels. These are scarce and do bring a premium. A small number of seconds were sold with their frames marked "IMPERFECT." These, too, have added value.
