Putting that postcode into 192.com came up with a "Director report" with a name at that address. It also came up with three names listed at "rear of 189A". I'm not sure that it is right to publish them here but they are easily found.
As for the aircraft the only thing that Google threw up was that it has been to Dunkeswell on five dates last september and also on 27/5/04.
Edit to add that they also own G-ATMM, G-BAEY, G-GKRG and have just sold G-BYBD to two Gentlemen from Derby who you might have more luck finding.
