The Royal badge is that of King George III and crests are those of Byng, for John, 1st Earl of Strafford G.C.B. (1772-1860).
These plates are described in the Manuscript Inventory of Pictures and Plate created Heirloom under the Will of the late George Stevens Byng, Earl of Strafford, December 1887.J.E. Boodle, Surveyor, 89 Chancery Lane, WC1: The Plate in the Custody of Messrs Garrard & Co, 25 Haymarket, SW1, 'thirty-six shaped gadroon dinner plates, 582.50oz.'
These Royal dinner plates may have been acquired by George Byng Esq. directly from Messrs. Rundell, who were responsible for the disposal of much of the Royal plate in 1808, in one of a succession of Royal sales - particularly of silver and plate - that took place between 1808 and 1843. The sales were triggered by the financially reckless pace set by George, Prince of Wales as well as his willingness to discard the outmoded and embrace the newest fashions.
