This is a scarce First Model Smith & Wesson .38 S&W Safety Hammerless Revolver a.k.a. "New Departure" or the "Lemon Squeezer". The revolver features a 3 1/4" barrel, five shot cylinder, grip safety, top break design, and a silver finish. 5,000 of the 1st Model were built in 1887 which featured the "Z-Bar" type barrel latch mechanism. The revolver incorporates an internal hammer and an external grip safety on its backstrap. Smith and Wesson tried a couple of different latches on the "Lemon Squeezer" before settling on the T-Bar latch which is found on all top break hammer revolvers. Besides being a 1st Model, this one has another rare feature. It sports an original factory silver plated finish; an option seldom found on Smith and Wesson revolvers made after the 1860's. Once the advent of more durable and less costly nickel-plating processes became available in early 1870's, silver plating was rarely used. Correct 1st Model patents dates on the barrel reading “Smith & Wesson Springfield Mass. U.S.A. Pat’d Feby. 20. 77. May 11.30. Sept. 11. 83. Oct. 2. 83. Two Aug 4. 85.”. Serial number is in the 3,000 range which is also correct for the 1st model. The mechanics are tight and function well. Serial Number: 3705. This firearm qualifies as an Antique, and does not require FFL Transfer or NICS Background Check.
