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 gnomon is missing from this sundial and the dial plate appears to be mounted above a previous plate of exactly the same size. The aligned Roman numerals are read from the inside using the form V - XII - IV - VII with a split noon. It has short hour lines with half and quarter hours also marked and with 5-minute divisions outside the chapter ring. There is a 16-point compass marked to NNE etc. There is a circular design at S with ’Deal Town Council’ in the centre of illustrations presumably of Deal town. Above the design is ’DEAL 300’ and below it, ’1699’ - 1999’.
