John Shelton, fl.1717-1777, was one of the most important clockmakers of his era.
In the 1760s he supplied five astronomical regulators to the Royal Society and the Board of Longitude, specifically for timing the transits of Venus between 6 June 1761 and 3 June 1769. All have survived. See photos of the example in the Science Museum
