Snipermtd24: You have a Post war .32 Hand Ejector, after 1957 these became the Model 30. Built on the I frame and later the improved I frame (I frame used a flat main spring, Improved I frame used a coil main spring). Serial range was 536685 to 712953, made between 1946 & 1960. Caliber was .32 S&W long. Barrel length should be 3.25 inches. The Improved I frame was introduced in 1953, if your gun has a screw in the front of the trigger guard and another in the front of the grip frame then it is an I frame. Without those it is an Improved I frame. In very good condition the Standard Catalog of S&W gave a value of $300 in 2006. Value is heavily dependent on condition however.
