This Lever Action No.1 Pocket Pistol manufactured by the New Haven Arms Company c. 1858. The pistol has the scarce plain receiver with silver-plated finish. The blued, .31 caliber, octagon barrel has an integral six-shot magazine with brass clam-shell follower, round muzzle, rounded T-bar spring and pinch-top front sight blade. The brass receiver lacks the factory engraving found on most No.1 Pocket Pistols and has the distinctive loading lever with finger hole, scalloped cut-out at the front of the ejection port and fixed, dove-tail mounted, rear sight. The hammer has deep, hand cut, knurling on the spur and a color casehardened finish. The rear sight, bolt, cartridge elevator, trigger and loading lever are blued. The two-piece walnut grips have a varnish finish. The top barrel flat is stamped with the legend: "NEWHAVEN CONN. PATENT FEB.14.1854" in one line. The serial number "1247" is stamped on the left side of the receiver beneath the grip. "1247" is stamped on the inside of both the replacement grips.
