I recently picked up a 4 inch square butt K-38. From what I can gather the gun was made in 1952. The serial number is K 1589XX The frame has 5 screws,The gun has a target hammer and trigger. The front sight on the gun has two pins at its base and the sight insert is yellow The gun is in excellent shape but does not have its original wood grips I would like to get the proper wood grips for the gun as well as any information on the gun. Any help would be appreciated
