The identity of the figure is not immediately clear, though it is likely to depict William III. Chargers showing this figure are usually uninscribed making identification difficult. Some are inscribed 'W R' for William III, an example of which was sold at Sotheby's, Olympia, July 5, 2005, lot 123, and even fewer are recorded with 'C R' for Charles II, see the example dated 1672 published by Leslie B. Grigsby, The Longridge Collection of English Slipware and Delftware, London, 2000, Vol. 2, p. 42, D.9.
Pot-painters were not so concerned with producing an accurate likeness, though in most cases on dishes inscribed C R, the painter has attempted a mustache that was worn by Charles II. William III was clean shaven but the depiction on the present charger is slightly ambiguous.
