The introduction of the first modern cab-over layout in the United States is credited to industrial designer Viktor Schreckengost, who, with engineer Ray Spiller, designed a cab-over truck for the White Motor Company in 1932. Schreckengost was later joined by other designers such as Raymond Loewy who designed the Metro series of vans and trucks for International Harvester. The bodies for these vehicles were initially produced by the Metropolitan Body Company (MBC). The company produced a wide variety of truck and commercial bodies for several vehicle manufacturers such as Chevrolet, Ford, Dodge Bros., and International Harvester until 1948 when they were purchased by the latter. MBC was instrumental in the development of COE route delivery bodies in the 1930s.
