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 appears to be a stone vertical declining dial which may be unfinished since it has no numerals. It is set into the brickwork with lead flashing below and two pins which point downwards from the top edge appear to be the only means of preventing it from falling forwards. It is probably meant to show the hours 10am to 7pm undivided. There is a dot by the 10am hour line, two dots either side of the noon line and a dot each by the 6pm and 7pm lines. The rod gnomon, which looks as though it were designed for about latitude 75° north, has a decorative scrolled supprt. The dial measures about 1300mm high by 860mm wide.
