Ok here is the pics I took. When Dan looked at it he stated it did not appear to be a refinish as well as one gun shop locally in AZ I took it to who offered 5 cash and 6 trade. I feel it's worth more and can sit on it awhile so any info you guys share is truly appreciated.
No indication of a S&W "factory" refinish. The only thing that is odd is the metal prep (as shown in pix you originally posted). On a 1960s S&W the metal preparation, before finishing, was a better quality than this one shows.
See the sand scratches on the butt by the serial number and on the frame along side and near the cylinder release button. If that was a 1970s S&W Masterpiece, I'd not have mentioned it. Being it's an early 1960s, that is unusual. Also, all the side plate screws have turn marks but that S&W Logo is clear, clean and sharp.
A quality refinish is not only a S&W Factory refinish. There are many able gunsmiths that do excellent and some even undetectable work.
The bluing, itself, is not any concern. It just seems the metal prep is unusual for an early 1960s Masterpiece.
Get a letter on it to verify the ship date and barrel length and you'll likely make a profit on it.
PS: to a Masterpiece collector that is a very nice, collectible, early model 48 ... but ... the hard core collectors would rather pay more to have one as new, or near new (with or without box). All these things that add to the value. If this were ANIB with all the papers and tools, you'd be good for at least double what you paid.
