Hello Baza
Perhaps worth trying English Heritage? In my dealings with Cheshire County Council, and West Yorkshire Archaeology Services, about the state of monuments in their area, both said that EH was the body to contact. I know Megaraks tend to have no respect for official heritage bodies, but given my success with the Bridestones, it might be worth it.
