Try asking Yeovil ATC; it's not too far away.
There was some discussion about Middle Chinnock (as it is listed in the Airfield Guide) on 'another forum' about a year ago and I think google maps came up with an address adjacent to the strip which COULD have been connected with a motor racing enterprise.
I wouldn't want to publish their number either in case it's wrong but if you search google maps you'll find it.
