Analysis of information sources in references of the Wikipedia article "Prince of Wales" in English language version.
the Prince of Wales is the only one who rejoices in the possession of officially assigned badges. The badge of the eldest son of the Sovereign, as such, and not as Prince of Wales, is the plume of three ostrich feathers, enfiled with the circlet from his coronet. Recently an additional badge (on a mount vert, a dragon passant gules, charged on the shoulder with a label of three points argent) has been assigned to His Royal Highness. This action was taken with the desire to in some way gratify the forcibly expressed wishes of Wales, and it is probable that, the precedent having been set, it will be assigned to all those who may bear the title of Prince of Wales in future.
