Patented by Walter G. Potter of Chicago in 1910, examination of the nameplates indicates that they were first manufactured by A.F. Wanner (1910–14), then Hacker Manufacturing (1914–1931). In 1931 Challenge acquires the Poco and Potter brands from Hacker; the 1935 ATF Catalog shows Challenge-Poco presses.
