Manhattan Fire Arms Co Navy Revolver
I think this is a series IV Navy Revolver. It has a 5" barrel and has a 2 line barrel address:"MANHATTAN FIRE ARMS CO. NEWARK N.J."
“PATENTED MARCH 8, 1864"
This gun is more grey than blue, and there is some minor pitting. Scroll work on the cylinder is visible. Grip varnish is about 85%. Gun has a tight a action. Is my identification accurate? Any idea what this gun is worth?
