One of the more subtle features of the gun is the actual colouration of the steel after it has been case colour hardened and subsequently brushed. All of our double guns and rifles go through the case colour hardening process as carried out by the St.Ledger brothers here in the old Birmingham gun quarter.
Before CCH the steel has a certain silver quality about it that is in basic terms raw and bright. The actual CCH process creates a surface hardness which allows the steel to flex under stress yet provides a protective outer shell or 'case'. When the fine surface layer of colour is actually removed the steel maintains a slightly more greyed tone which adds a real subtlety to parts that might otherwise look like a shined coin!
In direct sunlight it is often possible to see the very finest traces of colour which can be used effectively to enhance the engraving of the gun. Some engravers will insist on finishing their own work for this very reason. With Westley Richards, no matter who is finishing the gun or rifle, we always try to leave CCH on the triggers, action flats, action face, forend iron and inside the trigger bow. This always adds a tasteful touch, particularly when the gun is disassembled for travel. It also seems such a waste to remove them all!
