I have a revolver that's been passed down my paternal line. I understand it was likely owned by my great great grandfather John Allen Neese (~1844 - ?) from the Lexington, SC area. Or perhaps his father Allen Neese (1811-1881) before him. I probably have no way of validating its Civil War connection 100% but would love to get an expert's assessment on the make & model of this sidearm.
