This versatile firearm provides for an easy transition from black powder to center-fire cartridges. The gun's original frames were dovetailed to allow the ejector assembly to slide into place. A loading-lever screw, passing through from the left side of the frame, secures the ejector assembly. A small notch cut into the loading lever creates a rest for the L-shaped tip of the ejector rod. The firearm is steel with steel back-strap and brass trigger guard.
