I think this is a reasonable offer ,sounds like good people to deal with .
I fully believe the revolver pictured is a new gun , I don't think the factory spends a lot of time polishing anymore
The breech face shows no recoil marks that I can see
You can polish the gun yourself if the half done finish is bothering you
I know I would be breaking out the mag polish and enjoying the ownership of another fine 44
Ditto.
I had seen enough S&W stainless steel revolvers that look like that to believe it is in new condition. It seems like they don't make much effort to get all of the parts to match in appearance.
You could take the discount and then use the money towards having the gun hard chromed. This way you would have the ultimate in rust protection and have everything match in color.
