UFO 31 keel bolt mystery

Sorry to but in on a UFO34 site but I am trying to get some info on my UFO31. Does anybody know if Holman & Pye are still trading as I have telephoned several times without success. Alternatively does anybody know if the keel bolts on the 31 have galleries in the keel to enable withdrawal without dropping the keel.Enjoy sailing your 34's they are great boats!!Regards Terry k
