Well, I did a turnaround on this deal - I sat at the gun show all weekend helping at a table and using this opportunity to really check out some 1911A1s - Rock Island, Auto Ordnance, the Colt repro and Springfield. One guy had the real thing, an absolutely pristine WWII Colt for $1395. During all this, it gradually dawned on me that what I really wanted was not a Parkerized gun at all, but a pre-Series 70 commercial Government Model. Sure enough, there was one in the house - a 1953 in really nice shape - and the guy needed to move it out. I just finished a detail strip, cleaning and oiling on it, and it's first-rate and all-original, with about 85% Royal Blue and the original magazine. Bore is mint. I believe this gun had never been cleaned - it was that dirty. Before shaking on the deal, I took it to a well-respected former armorer who specializes in Garands and all pre-black gun U.S. weapons, and he pronounced it a 'good one'. Now for the bottom line - would you believe $600? The book on it goes to $1250 for VG, and this one would make that easily except for the grips - they're okay, but I've never seen any quite like them - they're like smooth grips with 'silver' Colt medallions, but they have a pressed-in wood grain pattern. They've been on the gun for a long time and could be original, but I put on a nice set of checkered, double-diamond grips of some kind of exotic wood that really looks great on it. I'll hang on to the old ones just in case they're for real. If the guy selling it had just done what I did to it, he could have gotten a lot more for it.
So, in case anyone else is still looking at the lower-priced 1911A1s, here's what I felt about them - they all looked okay. The R.I. finish was kind of hit and miss and the slide was not that tight. The Auto Ord. would have been my choice under $500 even though the slide serrations were slanted instead of straight up. The Springfields may be the best quality, but since the A.O. is now made by Kahr, that remains to be seen. Under $1000 you would have to take the Colt WWII repro (if you wanted a new gun. You can get a real WWII one for that). If you want a polish blued 1911A1, both A.O. and R.I. make one, and they look good, too.
One thing, though - when I asked the armorer about the imported 1911A1s, he highly recommended staying away from them. I have heard this from enough different sources that I'm starting to believe them. Time will tell.
