I've read a few times that the SAA was produced in the 3rd Gen with an all blue finish. I've come across a 2nd Gen .357 with an all blue finish that owner claims is orginal. The serial number puts the year of manufacture at 1972. The pics show the loading gate in a plum color like I've seen on older Ruger Blachawks. The feature that really stands out is the hammer is color case hardened. I'm skeptical at this point the gun is original. I would appreciate input on this one!
