Zep

Zep, manufactured by Shyvers Manufacturing Company of Chicago in June 1936, is an electro-mechanical (EM) pinball machine from a company that operated under that Chicago name from 1935 to 1937. Shyvers had earlier roots as a manufacturer based in Seattle before establishing operations in Chicago, then a major hub of the American pinball industry.

Little specific documentation survives about Zep's gameplay, scoring, or design. As an EM machine of this era, it likely used electromagnets, relays, and mechanical components typical of pinball games of the mid-1930s, predating the flipper by more than a decade.

With Shyvers Manufacturing Company's Chicago operation lasting only a few years, surviving examples of its games, including Zep, are relatively uncommon today. It offers a glimpse into one of the many short-lived manufacturers competing in the crowded pinball market of the 1930s.
