Central States Airplane Company was established in 1927 to build Don A. Luscombe's Monocoupe. In January 1928 the company became the Mono Aircraft Division of Velie Motor Corporation. Following Willard Velie's death in March 1929 the Velie interests were sold to Allied Aviation Industries a holding company. By May these interests were divided into two separate companies: the Lambert Aircraft Engine Corporation and the Mono Aircraft Company of Moline IL.
