I have been looking for a .44 or .45 2nd generation (standard SAA or New Frontier) for a while. When this showed up at my LGS I bought it after about 10 minutes of examination. I've been using George Garton's book on post-war SAAs to help me understand what's original and what's not. And it worked pretty good. The s/n, 66xxNF appears in all the right places as does the assembly number. No box or papers was included. Date of manufacture is 1970. Colt made 316 NFs in .45 with a 7 1/2 in barrel in that year. The LGS called it 98% but I think it's better than that. Can't wait to shoot it. Another great aspect of this buy was the price....$1235 out the door which includes the Cook County tax (for those of you not residing in the PRI (People's Republic of Illinois), Chicago in the primary population center for Cook County), an extra $25 firearms tax for God knows why. I'm guessing that New Frontiers are less expensive than standard models due to lack of demand. I don't really understand that but it got me a fantastic SAA for a price I never expected.
