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.
This dial was designed, delineated and hand cut by David Brown and has his logo ’dmb’ to the north of the vertical style. It is thought to be the only slate double horizontal sundial in existence whose whereabouts are known. Location information inscribed on the dial has been removed from the accompanying photographs, but it is designed for latitude approximately 51° N. It is made of Welsh blue-black slate, with a brass gnomon and stainless steel altitude index. It shows hours IIII - noon - IIII - VIII, read from the outside, with a Greek cross for noon, and divided to half and quarter hours. In the centre is a circular EOT curve.
The azimuth scale is divided to one degree, numbered in Arabic in 10s. The stereo grid is divided to quarter hours, with declination arcs at 2 degree intervals and daily ecliptic arcs.
To the south of the gnomon in a ribbon is ’DAVID M BROWN DELINEAVIT FECITQUE MMX’.
