Got a guy who wants to sell this gun. Serial # is N572xxx. Pics attached (not great quality...will try to get more). S&W customer service tells me it was made in 1979 (but nothing more than that). This gun looks like nickel, not blued. At this price he's selling it, if it's factory nickel, then it would be worth way more I think. Anyway, how I can tell if it came from factory nickeled or not?

thanks
