Mills worked on:
Alan's interest in watermills began in Kent when, as a lad, he was taken to visit the picturesque but derelict watermill at Westerham. He began recording mills in 1953, and has since built up an enormous and nationally significant collection. By means of photographs and measurements, notes from reminiscing millers and other local inhabitants, historical research and active preservation work, he has worked to preserve as much as possible of the character, traditions and technical details which the mills have been rapidly losing over time.
In 1969, Alan saved the largest of the waterwheels of the famous Tregarus china-stone grinding complex from under the nose of the scrap merchant by the collection of twenty-five tons of iron and steel scrap which he traded for the wheel!
During the 1970s and 1980s he acquired, restored and operated Venn Mill at Garford, Oxfordshire.
A considerable amount of research material on Kent mills generated by Alan, as well as by his father, Derek Stoyel, has been digitised as part of the Kent Millers' Tales Project.
