Genealogical Chart of Rolls-Royce and Bentley Motor Cars

Vistors to the Buckleton's showcase Motor House will have been struck by the amazingly elaborate and detailed geneaological chart of the complex ancestry and evolution of Rolls-Royce and Bentley motor cars which they have on display there.
The chart took an enormous amount of work by the Buckletons to research and specially to present graphically. It is far more detailed than the necessarily simplified story presented in this site's illustrated guide to Rolls-Royce and Bentley models. It also includes production numbers of models and estimated or known survival rates.
The chart is available exclusively on Winged Messenger On Line, in the form of a .pdf document. You will need Acrobat Reader to view it.
To give you some idea of the chart without downloading all of it, here is a small snapshot of a very small part of it. The full document is 461 kilobytes and may take some time to download.
