The "chief" or upper third of the shield bearing a lion passant came from the arms of Rowley Regis, and the "per saltire" division of the arms and green and gold colouring was found in Oldbury's insignia. The gold lions on a green background were from the arms of the Robsart family, while the crossed club and caduceus were the arms of James Watt. The crest featured a Saxon crown from which rose a green double-tailed lion, emblem of the Suttons, mediaeval lords of Dudley. The lion held an arrow from the arms of Matthew Boulton. The supporters of the arms were a red lion and dragon. The lion was from the armorial bearings of Sir James Timmins Chance, while the dragon was intended to represent the ancient Britons, founders of the "old burh" or Oldbury. Both animals held objects in their mouths as heraldic differences: an arrow (as in the crest) and an anchor (for Cradley Heath's traditional industry). The motto chosen by the borough was "Unity and Progress".
