DisgrifiadOS 1st edition 25in mapping shows a complex incorporating a large rectangular building and pump. Modern aerial photograph shows the site under heavy tree cover and a modern dwelling to the west of the road. However, LiDAR suggests that part of the industrial complex may retain some height under the trees.
