An important collection from the Estate of the late William John Thornton (1937-2025), of Groby, Leicestershire. 'John', as he was known, was an enthusiastic collector and scholar of early English clocks, and a dedicated member of the Antiquarian Horological Society, where he lectured on clocks at Keble College, Oxford, and contributed articles to respected horological publications. His passion for early timepieces—particularly lantern clocks and longcase clocks—resulted in a carefully curated collection that reflects both historical importance and technical excellence.
