I agree Fred ,Look's like if you would want to build a good copy that leaving of the roll engraving would be the easy part. I have an old 1970's era Griswold&Gunnison revolver that has the roll engraving on the cylinder . Sad part is the engraving look's really good if it were on a 1851 Navy. But just jumps out at Ya on the G&G.That Hoof did a fine job for Ya, a fine looking pistol.,,,,,Dusty
