Hi Philip
My friend cannot recommend highly enough Kevin O’Keefe, Unit 2, Old Bull cottages, Ledgers Road, Warlingham Surrey.
CR6 9QA. Not a million miles from you and apparently he often attends the Botley Hill Farm breakfast meet on the third Saturday of every month. Worth a run out to meet him?
Somebody else he has heard good things about but has no info on are Oxted based.
Good luck
Jonathan
