I am looking at a Performance Center revolver with a PC aluminum case and paperwork online which ends tomorrow. I asked the seller if the frame was freckled between the cylinder and the grip on both sides and between the front of the cylinder and the barrel or were the pictures just showing dirt. The answer was it was freckled. It is not pitted and is otherwise in excellent condition. It is a satin stainless revolver of very low production in an unusual caliber. The gun came from Louisiana which may explain its condition. Can this be buffed without ruining the finish and the gun's originality? Can S&W perform this work and how much would it cost? Thank you very much for your help.
