There is no official specification of how exactly the arms should look. Even the shield on the front gate of the late king's palace is different from the old black/white copy used by the (ex-) government printer on all official stationery, is different from the copy on the prime minister's office webpage, etc. Some have pointed crowns, some rounded; some have normal flags, others have flags looking more like banners; some use the modern orthography, some the old (Ko e Otua mo Toga ko hoku Tofia); some have black swords, others white; and so forth.
