Daryl, most of the gun seems to have stamped over numbers or whatever and they seems to be different numbers. The ejectors have the correct serial number. Is that a "F" following the number on the barrel? Seems to be awfully high quality damascus for a G grade. And the stamping dies all seem to be different! Could it be such an unusual configuration that many parts were just scavenged from others?
Just as a footnote, all these pictures were taken with an iPhone. Incredible macro quality for such a basic camera! Photos were taken about 6" away and then heavily cropped on the phone itself.
