OK. I have a revolver inherited from my grandfather. Barrell hinged at top. Six shot aprox 32 cal. Seems to be a rimfire. Serial num 46347. Cylinder marked with patent dates from 1855 to 1860. Six inch octagon barrell. Cosmetically in nice condition, almost looks like it could be safely fired. Very little movement in hinge, latch, and cylinder indexing. Simple trigger with no guard. Any help identfying would be appreciated.
