You can't beat that, it's a 2nd gen with removable cyl pin bushing. You'll have money left over to cut the barrel if you wish or at least get it standard roll marked and reblued, if that even matters to you.
1971 NRA Centennial (came with wood box and 2 papers) .357 Caliber 5 1/2" barrel, seemed unfired outside of factory. Great 2nd Gen SAA. Mine did not have gold inlay, just the barrel markings. I can't honestly recall what I gave for it. Understand that the Commemoratives do not follow market trends, they pretty much inch up over the years if well preserved, but not by much. Good shooters if you so desire but investment wise, you won't see em increase much in value.
