Bentley cars, despite being a subsidiary of Volkswagen, are still British made and are today based in Crewe, England. The Bentley, largely hand built, is a 'British luxury automobile icon' according to Wikipedia.
This book, Bentley Factory Cars 1919-1931, is described as the 'first definitive history of the Bentley golden era, and covers the personalities, the commercial and financial complexities, the engineering and development work – and the primum mobile of the company, racing.'
The book contains a chronological history, also covering events prior to 1919 where an understanding of them is required to appreciate later developments. It concludes at 1931 when Bentley Motors ceased to exist and Bentley Motors (1931) Ltd took over, acting as a subsidiary of Rolls Royce.
