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.
On the apex of the porch is this stone cube surmounted by a ball nearly as wide as the cube. One would expect to see dials on three of the vertical surfaces at least, but the maker has seen fit to supply just one West declining dial on the South face.The numerals are difficult to see but run from VI - VI in undivided hours. There are two prominent slits on the face which look as though they were once the fixing points of an earlier gnomon. It seems likely that when it was first installed it was canted so as to face due South but this must have displeased somebody who preferred it to be better aligned with the porch and tried to turn it into a declining dial instead. Each face measures about 250mm square.
[There is also a displaced mass dial upside down and very high on the north side of the east wall of the church, just below the roof line.]
