Footnote:

This Stop Watch would likely to have been gifted to Burgess by W.O. in 1929, when Burgess was forced to retire from Bentley Motors due to ill health. There is little doubt that this Stop Watch, in excellent working order, would have been used by W.O. at many of the great Bentley races during the 1920s held at Brooklands, Le Mans, Newtownards TT and Phoenix Park. A photograph of W.O. Bentley sitting in the pits at Le Mans 1928 with his Stop Watch appears in Vol 11 of Clare Hay’s ‘The History of Bentley Motors’ p. 447.
