In the DGJ article by Bill Wise telling about his son, Ben, winning the Vintage Cup hammer gun competition with his Greener Royal, nothing was said about the mentioned characteristics of a Royal. Ben's Greener was plain and unengraved and Graham Greener apparently identified it as a Royal. In emails to and from Graham Greener, inquiring about my eight gauge hammer gun unengraved and identical to Ben's gun, Mr. Greener identifies Ben's gun as a Royal and identified my gun as best grade, but unengraved. I left our conversation assuming that both Ben's gun and mine were Royals. Apparently, the build cards at Greener don't always identify a gun by grade. I don't know anything about the catalog listings for Royals, but would be interested in hearing about them. Neither Ben's gun or mine have grade markings on the trigger guard.
