I don't know, but I love the minimal class A engraving. Some times wide open spaces makes you appreciate the engraving more rather than being overwhelmed by it. Like that Townes Van Zant song that goes, "There ain't no dark 'till something shines...". I can only recall two Colts, both Sheriffs Models, that I've seen in books engraved by him. One a Texas themed one in the Doc O'Meara SAA book. Uh hmm. You know, a left hander should really own that gun.
