I would like to know the value of a SF-VI LNIB with all the papers, hard blue case and cardboard sleeve. It's matt SS and a bobbed hammer. I was told less than 30 rounds through it, and it has no line on the cylinder like some that have been shot after a few hundred rounds. How rare are these? I'm told less than 10,000 made and only about half had bobbed hammer......REALLY? Thanks for the feedback.
