12 ga. Sawed off Percussion coach gun

Here is an antique 12ga. Percussion shotgun. Shortened guns such as these were used in the Civil War with great effect by confederate cavalry. They were also use to guard gold bullion on stage coaches and trains in the mid 1860s and on into late 70s in the West until they were replaced by the cartridge shell versions. These were used by Wells Fargo, Adams and American Express companies as well as the railroads. The coach gun was carried right along with the Wells Fargo strong box. This gun was a very inexpensive shotgun and is very plain. It looks to me that the nipples have been replace and fired in the recent past.  This is a very rugged old shotgun with 18 inch barrels and is 34 1/2 inches overall including the ramrod. The stock is in remarkable good condition and may have been replace by someone who knew what they were doing. So, it shows no handling dings and no breaks or cracks, which are often found on these old double barrels. It would look right in place on a frontier stagecoach or on board an early steam train express car.
For it's age this gun is very well preserved and would provide a century of service yet.  There are no makers marks that I can find.  In the center of the rib it says, “FINE  TWIST BARRELS”.
