Looking for Donald Weslake original owner of my 51A

Hi all

The Lotus 51a that I am now the proud custodian of, was originally sold to Jim Russell Racng school and then within in months a Donald Weslake bought the car ran it for two years and then parked it up until it was sold in 1996. I would love to know where and when it was raced and if any pictures exist of it in its heyday. And if possible get a copy of some programs from back then from meetings in which it raced.
Apart from the name I have nothing else to go by, does anyone know him, or of him or have any other details that might help me.

Would love to complete the history of the car with this information.

Cheers John
