From the serial number it appears to be a 38 Double-Action 4th Model, which, according to the Standard Catalog of Smith and Wesson, was manufactured from 1895-1909 (Serial number range: 322701-539000). The condition seems to be Fair-Good, with a value of $200 plus or minus. However, those beautiful grips add considerably to that. They are probably worth $125-150 (assuming no cracks or chips). You'll get other ideas of value by those more expert than me. Be very careful if you decide to remove the grips - they are fragile.
