The Coat of Arms

The TRE KRONOR and its coat of arms

At one time the coat of arms belonged to the absolute pride of the Swedish fleet: the Tre Kronor.
In 1557 the ship was dispatched by the king, but it never returned from its journey. For 500 years, the Tre Kronor was assumed to be missing, until Captain Finn Olsen fished the coat of arms from the sea on the Swedish coast in 2015. By royal order, the Tre Kronor had set sail in 1557, searching for the magical island of Rulantica.
Does finding the coat of arms prove that the Tre Kronor’s mission was successful and that they actually found the island?
