Welcome to the S&W Forum, I see the picture, and it appears nickle plated. If that is an original finish. The grips are not original, which is a negative, and the finish appears dull, which is a negative. This is a 2" snub nose, which is a positive. If it is mechanically good, and the barrel and chambers are clean (not rusted or pitted) the $400 est may be a little high, but not too much. A good cleaning and if you want to bring out the shine of nickle, you could polish it with a soft cloth and Flitz, or one of the other metal polishing pastes. Rub gently,old nickle finishes can be a little thin.
