The titlepage to Sayers's pamphlet (op. cit.) includes the note '"We understand that Mr Nollekens is now employed in modelling a bust of Lord Grenville, as a companion to those of Mr. Pitt and Mr. Fox." Daily Papers'. "This identifies 'Lord G******le' as William Wyndham Grenville, baron Grenville (1759-1834), of whom Nollekens did indeed complete a marble bust in 1810 (now in the Royal Collection).
