Sold for $747,500 at 2021 Bonhams : Quail Lodge.
In 1927 Walter Owen Bentley replaced his 3 litre car with a more powerful one by increasing its engine displacement to 4.4 liters (270 cubic inches). The publicity brought by their competition program was invaluable for marketing Bentley's cars.

This 4.5 liter Bentley, originally owned by Thomas Ryan, was raced during the early 1930's and at some point, the engine seized. Another 4.5-liter engine (FB 3311) from the same year was sourced. The current owners, who purchased the car in 2011 began searching for the original engine. Eventually, that engine was discovered and reunited with the chassis. This has been documented by Dr. Tim Houlding, a Bentley historian at Vintage Bentley Limited. In addition to that engine, the car carries its original 'C' type gearbox, rear axle, and differential.

The restoration was completed in March of this year. The car is a mechanical mate to the winner of the 1928 24-hour race at Le Mans.
