The Arms of the Company were designed by Sir Colin Cole, Garter Principal King of Arms, and presented by him at the Installation ceremony of Alderman Sir Peter Gadsden, the Guild's new Master, in 1987. These Arms depict five purses symbolising trade between the five continents, with the sword and wheel of St Catherine together with the water and quayside of the dock, as a reminder of the company's foundation. The Arms are surmounted by a carbocle containing a medieval merchant's cap and the supporters are a dolphin borrowed from the Company of Watermen and Lightermen, who originally gave the company sanctuary in the City of London, and the sea dragon of the City as a mark of respect for its commands.
