UPDATE: This post now includes the full brochure, along with updated information about the company.
Wausau Iron Works, unsurprisingly, incorporated in Wausau, Wisconsin, as an offshoot of the Northern Boiler & Structural Iron Works out of Appleton. The founders launched Wausau in 1908 to build bridges (some of them here), but expanded into snow plows in 1923. During WWII, some of the company’s plows were turning to the military.
Oddly enough, there was an earlier “Wausau Iron Works” was founded by Ely Wright in 1874. It was the oldest industrial establishment in the city and supplied machinery for the early railroads and for sawmills in north and central Wisconsin. However, I could find no evidence it made snow plows.
