Buried in Brophy's book is one sentence that states there are no known examples of double barrel guns with ventilated ribs that have precious metal inlays. Virtually all SBT guns from Eagle on up have inlays with their VR's; also most Specialtys have silver inlays; most lower grades have none; no Olympic SBT's have been noted with inlays. When I find the page in Brophy I will post it
