The Remington-Rider New Model belt revolver was part of the famous Remington Model 1858 revolver pistol series (detailed elsewhere in this site). The gun stemmed from a partnership between Remington Arms and Joseph Rider of Newark (Ohio) and saw service in the American Civil War (1861-1865) when any and all firearms were sought by both sides. The Remington-Rider lays claim as being the first Double-Action (DA), cartridge-based revolver in American firearms history.
The gun was of a large, solid-framed design typical of Remington hand guns of the period. Original forms fired from a percussion based system involving the hammer and percussion caps set upon "nipples" and this was used to ignite the awaiting propellant charges. The early production forms were chambered for .36.
Manufacture began in 1863, with the Civil War in full swing, and ended in 1873 after about 3,000 to 5,000 pistols were completed. All were fashioned with 6.5" barrel lengths and the cylinder was either smooth-sided or fluted. When cartridged ammunition became more-and-more the norm, conversions of the weapon were had and this produced the same weapon in .38 centerfire chambering.
The Remington-Rider held several unique design elements as revolvers of the period went: the chamber, in particular, was of a noticeable "mushroom" shape which tapered from the frame towards the cylinder rear. The trigger was nearly straight in its appearance and the grip handle elegantly formed. The trigger loop was of an oversized design. All other qualities of the gun were representative of the era, however, including the exposed hammer at the rear of the frame and the loading lever set under the barrel.
