ROMAC: thanks for the explanation. Very informative.

All of the guns are nice but one, a 20 ga. Purdey, is especially nice. Has their economic value now been drastically reduced by the symmetrical, non-blued spots on each side of the barrel? I certainly don't like the way it looks but I'm not too worried about their value as I won't be selling them but my heirs, none of whom hunt, might be concerned. I assume re-bluing would be frowned upon?
