I will try to help you with this.
It may be very difficult to obtain records from that far back. Most will have a duty to retain them for a certain number of years before they are passed to the National Archive. I think your first point of call must be the Court itself. Their general enquiry number is 02476 630 666. Give them a ring and explain the situation and hopefully they should be able to push you in the right direction.
Failing that we can take a look at the National Archives.
Let me know how you get on with this first.
