That Colt logo engraved on the USFA frame would have been the deal killer for me, too.
For the life of me, I can't understand why so many USFA owners go to lengths to make their USFA guns look like they came from Colt. Sometime back, on this forum, someone posted pictures of his USFA that he had fixed Colt grips to (he was bring to sell the gun). I made the comment that "Putting Colt grips on a USFA is like putting Volkswagen hubcaps on a Mercedes." Really ticked him off at the time! As comments go, it might have been a bit extreme but none the less, if you want a Colt, buy a Colt. Don't denigrate a USFA by trying to make it look like something it is not.
