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 corner of the porch rather than above its centre is this slate dial which is now in a very poor state. It must have been handsome once and Mrs Crowley managed,in 1956, to draw its decorative border and a shield surrounding the gnomon root. The outline of the slab has straight lines at the bottom and sides with decorated corners and top. The dial plate itself has been described as elliptical but it is very close to being circular, which is how the 1956 drawing depicted it. It show the hours VI to VI divided into halves. The gnomon has an S-shaped supporter and is a replacement. It measures roughly 750mm square. The dial is not dated though Mrs Crowley suggested that it was late 18th or early 19th century and I don’t think we can get closer than that.
