Pilot Mill

The company did not hold the property long before they sold it to the Belk-Hudson Company in 1931. A little over 30 years later, the Crompton Company bought the mill and operated the mill to its full capacity until they closed the doors in the late 1970s. The mill was then used as a warehouse until the property went up for redevelopment in 1988.
