The serial numbers on the grips and grip frame match. These pocket pistols along with the Navy pistols and carbines produced at the same time by the New Haven Arms. Co. mark an important step in the evolution of repeating firearms. They were the final step prior to the iconic Henry rifle and share many attributes with the later design which was essentially a Volcanic redesigned for .44 Henry rimfire cartridges.
