Description:Members of Staffordshire Industrial Archaeology Society excavating the iron mill wheel which drove a water powered threshing machine at White Barn Farm on the Shugborough Estate. White Barn was built around 1770, and was redesigned by Samuel Wyatt in about 1805 when Shugborough Park Farm was built. The threshing mill was designed by Andrew Meikle and installed by Samuel Wyatt around 1805 and seems to have become redundant by 1850. The machine was capable of threshing 200 bushels a day.
