The S&W Model 67 is a stainless steel K-frame .38 Spl with adjustable sights. The rear sight is the standard S&W black adjustable sight. The tip screw is the elevation screw. The right side screw is the windage screw. The left side screw is actually the nut that secures the windage screw. The Serial number is the one with the "k" in it that appears under the crane and on the butt. I do not have access to the master list, but yours was probably made in the mid to late 70's (maybe early 80's). The 67 is a good serviceable revolver. The frame is the same as the .357 Mag Model 66, but do not attempt to load Magnum ammo in it. IMHO it is safe for a steady diet of +P ammo.
Word of advise---Do not attempt to remove the frame side plate (right side) unless you know what you are doing. It is not a difficult proposition, but you can bugger it up if you are inexperienced.
In life, strive to take the high road....It offers a better field of fire.
