Much of the milling machinery is intact. The mill operated until 1940, and retains most of its milling machinery. The body contains all the milling machinery. The mill retains its original mill race and milling machinery. The mill had a large water wheel to drive the milling machinery. Smith became determined to have milling machinery constructed, disassembled and hauled overland to Pikes Peak. Hillje later enlarged the plant with regular milling machinery for cottonseed. Some of the milling machinery which had been removed over the years was recreated. All the milling machinery is housed within the body. Originally, Ingersoll Machine Tools focused almost entirely on milling machinery and processes for metal removal. The sails and milling machinery have been restored, as have the miller's living-quarters. The mill still contains the original milling machinery, which is in operable condition. However, the milling machinery had to be shipped from New York around Cape Horn.
