From a collectors standpoint if you have the cash its worth it. From a functioning standpoint a S&W revolver worked on by a quality gunsmith will perform just as well for a fraction of a price. I would rather drop that kind of money on an entirely handmade Arrieta shotgun, at least with the Arrieta you get custom engraving and some of the nicest wood furniture you will see on any gun.
I know this is the revolver forum but if you are interested in Arrieta shotguns this video does them a great justice, an absolute work of art, literally.
