Sometimes the info on the cards is incorrect or incomplete also. I once bought two Fox guns that the previous owner had requested letters on. Both were 12 guns. One was an AE grade and the letter said the card was lost. The other said the gun was a Sterlingworth 2nd. However the "Sterlingworth" was engraved to at least the C level, had ejectors and a straight grip stock and extra length forend of highly figured wood. Numbers match on the gun, stock, forend and straight tang trigger guard. All work appeared to be factory done. The frame was not marked with a grade stamp. How such a piece came to be is only speculation, since it appears to be factory work, but doesn't match the card.
