William Plummer was apprenticed to Edward Aldridge, clothworker on 4 February 1746. He was free on 5 February 1755. His first hallmark is entered as a large worker on 8 April 1755. Address: Foster Lane, then on to Gutter Lane on 11 September 1757, where he appears as plate worker in the Parl. Report list 1773. His son, William, is apprenticed to Thomas Whipham as goldsmith in 1777, when William I is described as Citizen and Clothworker. His work is almost entirely confined to pierced saw-cut pieces, such as: cake baskets, sugar and cream baskets and strainers. He must have had a reasonable sized establishment, as piercing is of necessity a slow process, and, from the survival of his pieces, the output must have been high.A consistently fine maker.
