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 on the porch is a ghost of its former self. Mrs Crowley in 1962 managed to see the oval dial plate with its long axis vertical in the middle of the rectangular slab of slate. She showed the hours VI - VI and the motto "Tempus Fugit" above them. It is a surprise to find that an indifferent photograph reveals a lot more when examined with a magnifying glass. There is intricate scroll work surrounding the oval and just above the root of the gnomon is engraved, Lat 50° 57’ which is actually about 30’ adrift. Round the gnomon support there is an eight-pointed star, the hour markers have a dotted cross at the end and the hours are divided into halves and quarters. After midday the dial is in shade.
