bronz1924, I have a nickel M29-2, 4" and you could not buy mine for anything close to what they are asking for theirs. You have gotten some great advice, but one more thing, make sure that there are no areas where the nickel is peeling or starting to turn loose from the frame. Could be just a small area, but once it starts to peel, nothing can stop it. Cloudy or milky areas will, for the most part, polish out. Good luck with the purchase, and we will want to see pics.
