Someone above suggested starting from other than a Fox; here is what we did with a D M Lefever Sons & Co crossbolt 12 which had been restocked poorly and was rusty and with no remaining original finish when I got it. It is an ejector gun, as are all but the lowest grade cross bolts, so I can't add anything to that portion of the discussion. Styling cues were taken from both high grade cross bolt guns and from the earlier Lefever Arms Co guns.
