Manufactured from 1870 to 1872, this model, was the first top break automatic ejecting revolver that Smith & Wesson made and also the first large caliber revolver that the company made. This revolver serial number "76" is a first year production gun which also features an "oil hole", as found on the first 1,500 or so of this model, located on the rear of the extractor housing on the bottom of the barrel lug. The top of the barrel rib is marked with the one line address and five patent dates (1860 - 1869). The rear face of the cylinder, right grip frame and the barrel latch are marked with the assembly number "J3". Blue barrel, frame and cylinder with casehardened hammer and trigger guard. Fitted with smooth, two-piece walnut grips.

Fine. 50% thinning original blue finish remains on the barrel, strongest in protected areas the balance is now an even gray patina. The barrel address is still crisp and clear and only minor handling marks and surface scratches are present down the length. The frame retains a strong 75% original blue finish thinning along high edges with surface scratches and dings scattered. The cylinder still retains strong original blue finish. The hammer and trigger exhibit flashes of brilliant case colors mostly in sheltered areas. The grips are very fine with only a few gentle pressure marks. Overall a very solid, totally original first year production 1st Model Smith & Wesson American.
