Welcome Hugh,
There's a mob out here in Australia called Pearlcraft, whom I understand are very good - perhaps others with direct experience can verify?
Their web site is here
www.pearlcraft.com.au/welcome.htm
They used to have pictures of a Bristol steering wheel on their site but they were poor quality photos which is probably why they have taken them down. However they have many other "before and after" pics at

PS. It looks like they should stick to restoring steering wheels and leave the web site development to someone else
