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 was replaced in 192x (the original is still to hand though not useable for a UK latitude). The dial is said by the owner once to have stood outside King John’s Hunting Lodge, Tollard Royal, Wilts. Access only with prior permission.
