The Parris Manufacturing Company of Savannah, Tennessee is an American company that primarily manufactures toy guns.
Iowa inventor William G. Dunn (1883–1968) originally owned a hardware business in Clarinda, Iowa. With the start of World War I, Dunn created the Dunn Counterbalance Company that operated out of the hardware store until he built a factory in Clarinda and renamed his company the Dunn Manufacturing Company. Dunn was responsible for 48 patents, 7 to do with wind power. The Dunn Manufacturing Company also built a 3-seat Cruzeaire Monoplane in 1928.
In 1936 Dunn teamed up with Cecil Lewis "Catfish" Parris, a marketing specialist, to form the Parris-Dunn company. The company was formed with Parris as President and Dunn as Vice President to sell a wind driven generator for farms to recharge electrical items. The Dunn Governing Principle was able to use a controllable propeller speed with fewer moving parts than other wind generators.
