For interest, The Napier-Railton is an aero-engined race car built in 1933, designed by Reid Railton to a commission by John Cobb, and built by Thomson & Taylor. It was driven by Cobb, mainly at the Brooklands race track where it holds the all-time lap record (143.44 mph (230.84 km/h)) which was set in 1935. Between 1933 and 1937 the Napier-Railton broke 47 World speed records at Brooklands, Montlhéry and Bonneville Salt Flats in Utah. This lot was entered by a local vendor, the son of a tool collector but unfortunately we have no more provenance. We have no guarantee that they relate to the car at Brooklands.
