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.
Pedestal 1600mm high, on four steps each approx 300 high, so difficult to see. Aligned Roman numerals read from inside. No other details visible due to verdigris. 4-tab riveted gnomon support.
