If you'll look at Cabela's Gun Library site, they have a Perazzi for sale with, "two small case-harding chips". I wondered about it myself, however they got photos. I can't imagine tht case-harding is thick enough to able to chip off. I don't quite understand.

PS: I like that "fish" after my name. I saw someone else on this site use it. May the Lord bless us all.
