From 1883 the school was accustomed to use as a coat of arms the version of the Wilson shield used by Edward Wilson, probably without authority. In 1985 the then Chairman of Governors, Lt. Col. W. R. Bowden, obtained a Grant of Arms from the College of Arms. The new officially authorised Arms introduced to the previous form a silver bar between the wolf and the objects above, together with a gold border. Additionally, a crest is added above the helm in the form of a black wolf holding a silver fleur-de-lys in his paws with a black and gold mantle.
