Tolong jelaskan mengenai 1933: Rothesay dari Edward VIII dalam bahasa melayu

Edward's coat of arms as the Prince of Wales was the royal coat of arms of the United Kingdom, differenced with a label of three points argent, with an inescutcheon representing Wales surmounted by a coronet (identical to those of Charles, the current Prince of Wales). As Sovereign, he bore the royal arms undifferenced. After his abdication, he used the arms again differenced by a label of three points argent, but this time with the centre point bearing an imperial crown.
