1931 Riley Nine Brooklands
- Engine
- Riley Works racing inline configuration, same specification as Irish Grand Prix entries of 1930-1931

A Riley Nine racing chassis (no. 8046), built to the lightweight aluminium-bodied Brooklands specification and developed at Thompson and Taylor to the brief of Parry Thomas and Reid Railton, this car was equipped with a Works racing engine of Irish Grand Prix specification. Sold new to British racing driver Whitney Straight in 1931, it passed through several documented owners including Denis Jenkinson, who raced and modified it in the 1940s. Extensively researched and restored to its Straight-era configuration by a later owner, it has competed at the Le Mans Classic, Le Mans Legend, and the 2009 Monterey Historics.
