It's a 6" N serial numbered 27-2.

Not interested in selling it. Thanks though. What I really wanted to know was if I could have it restored with the same exact type of front sight it has. I don't know if S&W would do this kind of work these days????? And if they could do it, I don't know if knocking that blade and the pin out will cause enough damage to the surfaces to look boogered up requiring polishing and a full gun reblue.

I assume when the gun was built, all that work gets done first; The new blade front sight and pin is installed, polished smooth with the surface, and then the bluing is applied. I'm guessing to bring it back to like new condition, they would have to replace those parts, polish the metal smooth so you can't see the pin ends, and then reblue the entire gun. I'm not a smith, and just guessing. Correct?
