These are the arms of the London Clothworkers' Company. Havettes, also known as habicks, were hooks used to attach fabric to the forms on which it was stretched for teaselling and shearing. The teasels were used to raise the nap of the fabric prior to shearing. The best woollen cloth was raised and shorn several times.
