Found in S Louisiana near a waterway in an area with civil war/antebellum activity. I've identified this as an 1865 Remington pocket revolver. The wood is in fantastic shape somehow, but as you can see the chamber and barrel got the worst of it. Electrolysis and patience have gotten this far... Anything else I can do to remove the corrosion or is this it? Maybe evaporust bath? Any thoughts are appreciated!
