Manufactured from 1868 to 1875 this is very nice example of a Model 1 1/2, 2nd Issue revolver. The top of the barrel rib has the one line address/patent dates (1855, 1859 and 1865) marking. It has a five shot fluted cylinder, casehardened trigger, hammer and ejector rod and nicely figured bird head rosewood grips. The right grip panel is numbered to another gun.
