Sir Henry 'Tim' Birkin 1929-32 Bentley 4½-Litre Supercharged Single-Seater

It's not news that this car was sold this year as the most expensive Bentley to be sold at auction.



It is an amazing car.



Here is the auction summary from Bonhams.



What I have managed to find is another period photo, not of the car on the track, but at Cricklewood!



Oh look, those young boy hands are being put to good use on the small fiddly bits on the supercharger.

Good work young chap. I wonder what he got paid for for working on a £4.5 million (US$7.05 million) car.
