The eighty sixth image is a large photographic print of the millstones of an unidentified mill. There is no recorded date of production. The photographer is recorded as "K. Wilson". Owing to their relative size, the large photographic prints have been placed in a separate folder entitled "E. M. Gardner : EMGC-04-18 - Large Photographic Prints."

As Gardner describes, the thirteenth photograph is an image of a millstone and stream in Sheffield. However, the mill pertaining to the millstone and stream is unidentified.
