BRIDOL is the British Sundial Society's Register of Fixed and Mass Dials, which gives detail and photographs of about 8000 fixed sundials and 3000 mass dials in the UK.
Some of these are in private gardens, but the majority are publicly available.
It is difficult to see much on this dial but some careful cleaning would make everything clear. At the top is the motto. "See how swiftly Time does fly, Be prepared O Man to die." A semicircle round the root of the gnomon has the partly legible names of the churchwardens WBB.... And JBF... with the date 1786 (according to Mrs Crowley’s drawing). Beneath is "Tempus Fugit" . The dial plate has numerals VII to V though half and quarter hour markings extend to where VI and VI would be found. The dial is inset into the wall and slightly canted. The gnomon is a replacement. The dial measures 610mm square.
