Grist Mill Auctions

In the early 1900s, this building was local businessman George Hancock's blacksmith shop. The building suffered two fires (1943 and 1948), but was rebuilt. Then it was a feed mill for a time. It has been flourishing since 1980 as part of the Stapleton Auction house. It also features a rare 1930s Ruston & Hornsby diesel engine.
