Manufactured in Brooklyn from 1861 until 1863, Moore's revolver was a 7-shot single-action piece firing .32 rimfire cartridges. What makes it unique is its swing-out cylinder design - the first commercial revolver in the US to use this mechanism. A latch on the back of the frame released the entire barrel and cylinder assembly, allowing it to tip over to the right, exposing the chambers for loading and unloading. The ejector rod is stored under the barrel, but must be removed and used by hand when needed. Moore's revolvers were popular with New Yorkers heading off to the Civil War and almost 8000 were made, but production was halted when Rollin White successfully sued for patent infringement (over his patent on the bored-though cylinder).
