Nice gun. Mine was a good shooter. Built on the Gold Cup frame with flat rib on slide, minus the GC serrations. Wide trigger, but without the GC adjustment screw. Flat black finish. It could be looked at either as a enhanced Mark IV Series 80 or a poor man's Gold Cup. Limited production, so Colt collectors might be interested. Not really special, but they're not making anymore and they won't go down in price.
