I recently picked up a Remington 1858 New Model percussion revolver and have some questions about it - this not the type of firearm I usually get involved in. The revolver has been modified by the addition of a front sight with barrel band and a dovetailed rear sight. The grips or stocks are modern replacements. What is curious about this revolver is the numerous markings on it. On the right side of the barrel near the frame it is stamped with the letter H and then on the frame in front of the cylinder, an inverted W that may have been meant to be a M. On the left side it is marked with a D on the barrel, a R on the frame in front of the cylinder, a R on the rammer and a W at the rear of the frame behind the recoil shield. The W also appears on the bottom flat of the barrel in front of the rammer and there is an R just behind the trigger guard screw. What I assume to be the serial number, 99365 is marked on the bottom flat of the barrel but is covered by the rammer and there are markings or numbers on the butt. The top of the barrel is marked "Patented Sept 14 1858, Remington & Sons Ilion New York USA New - Model" in three lines. The revolver is good and tight and operates correctly with a near excellent bore. the nipples while slightly corroded, are in good shape and not battered beyond use. So I wonder what the markings might indicate. Was it an issued Civil War revolver? No inspectors marks that I can see but again I am not familiar with these revolvers. I will try and get some pictures posted soon. Thanks for any comments!
