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.
The dial is at the top of the wall of the south porch on the tympanum , about 10 m from the ground.
The upright Roman numerals are blue and run from 7am to 5pm with half hour divisions. The hour lines are red and half hour lines blue and they join to a red semi-circle around the gnomon foot.
The lower edge of the gnomon is fimbriated with elegant curves, and has a nodus notch. An equinox line forms the lower edge of the dial.
It is possible the makers were John and William Bastard, local architects and builders of the church which dates from the 1730s following the Great Fire of July 1731
