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 hangs on an indoor wall and receives sunlight only between mid-late February and mid-late October. It shows 12 noon to 9pm with upright Arabic numerals, divided to half and quarter hours, with solstice and equinox lines.
Ref: Bulletin 35(i) March 2023, pp 2-5 has a full account of the construction.
