What confuses me is that if it was stripped and polished, it was an absolutely masterful job. No blurring of the markings at all. I've had it about 10 years or so, so I have no history on it. The finish is more matt than polished. I'd expect a polished finish if it were chromed unless it were done after market and bead blasted first. If that's how it was done, the entire pistol was stripped to its component parts before the bluing removed and the aftermarket finish applied. Could it be a 67 with an incorrect stamp? It has blued rear sight and red insert in the front ramp.
