I looked into our Paul's purchase of an Aston Martin DB6 in 1966. According to the Aston Martin website: www.astonmartins.com/db4_5_6-s/db6.htm , Paul took delivery of the car in March, 1966. There is also a mention in Maureen Cleave's article about our Paul published in The London Evening Standard, March 25, 1966, that Paul was driving his new DB6.
I've searched Google images, though, and I have not found a credible image of our Paul in or near that car. However, I have found several images of Faul in and near the car, including Mal Evans' home video shots of Faul in Spain (probably) or Kenya.
