I have been told that if a gun was ordered through smith in nickel, sometimes they would take a blued gun and re finish in nickel. they would even restamp b-n or a star. would this gun letter as blued-nickel-refinish-other?.i just saw a gun that was not offered in nickel but has a star. I am thinking of buying this gun and taking a chance that it may have been ordered that way not sent back( because of other rare features). if it lettered nickel it may be one of a kind. if not i will have paid way too much for a renickel...thanks
