The only solid excerpt for this windmill comes from the Historical Society of Peotone, constructed by H. H. Depner:
A wind-mill, a short distance north of town, built by Henry Ditmers' is worthy of mention. The mill is now owned and operated by Herman Ehlers. It is built on the Holland plan, runs two sets of buhrs and is used for grinding flour and feed, most of which is custom work.
