Intermountain Manufacturing Company

Intermountain Manufacturing Company, commonly abbreviated IMCO, was an American aircraft manufacturer active during the 1960s. The company was based in Afton, Wyoming, and specialized in agricultural aircraft. Its formation followed the failure of the Call Aircraft Company: in 1962, Intermountain Manufacturing Company acquired Call Aircraft's assets and used them as the foundation for a new manufacturing operation. The acquisition gave IMCO access to the designs and production resources associated with the CallAir aircraft line. In 1963, IMCO began new production of the CallAir A-9, an agricultural aircraft intended for work such as crop spraying and related farm aviation tasks. The A-9 represented the company's principal production aircraft and connected IMCO to a specialized but established segment of the American general-aviation industry. Rather than functioning as a broad consumer brand, IMCO operated primarily as an industrial aircraft manufacturer serving agricultural operators and other users of purpose-built utility aircraft. The company also developed a larger and more refined aircraft derived from the A-9. Designated the B-1, the aircraft extended IMCO's product activity beyond simply restarting production of the inherited CallAir design. The B-1 is associated with the company's effort to improve and enlarge its agricultural-aircraft offering, although the available reference material does not provide detailed production totals, sales figures, performance specifications, or a complete account of its commercial reception. IMCO's independent existence was brief. In 1966, Aero Commander, then a division of Rockwell International, purchased the company. Production was subsequently relocated from Afton to Albany, Georgia, in 1967. The acquisition and relocation ended the company's operation as an independent Wyoming-based manufacturer and integrated its aircraft-production activities into the Aero Commander and Rockwell corporate structure. The available sources do not establish a separate continuing consumer brand after the move, nor do they identify current successors, surviving corporate operations, financial results, or a present website. Intermountain Manufacturing Company is therefore best understood as a historical aircraft-manufacturing company rather than an active contemporary brand.

Intermountain Manufacturing Company was a Wyoming aircraft manufacturer of the 1960s whose business centered on agricultural aircraft. The company was formed in 1962 after acquiring the assets of the failed Call Aircraft Company. This transaction transferred the relevant production resources and aircraft lineage to a new organization based in Afton, Wyoming. The company's first documented manufacturing step came in 1963, when it began new production of the CallAir A-9. The aircraft was designed for agricultural aviation, a field in which specialized airplanes were used for crop spraying and other farm-related operations. By restarting production under its own corporate identity, IMCO preserved and commercialized the CallAir product line rather than developing an entirely unrelated aircraft family. IMCO subsequently worked on an enlarged and refined derivative known as the B-1. The B-1 reflected an effort to develop the inherited aircraft concept into a larger and improved agricultural aircraft. Available historical material identifies the model and its relationship to IMCO's product development, but does not provide enough information to establish detailed specifications, production volumes, customer lists, pricing, or the exact duration of B-1 manufacturing. The company remained independent for only a few years. In 1966, Aero Commander purchased IMCO. Aero Commander operated as a division of Rockwell International, placing Intermountain's aircraft activities within a larger aerospace and industrial group. In 1967, production was relocated from Afton to Albany, Georgia. The move marked the practical end of IMCO as a standalone Wyoming manufacturer and consolidated its manufacturing operations within the acquiring company's structure. No reliable source supplied for this dossier documents a later independent corporate identity, a modern successor brand, public listing, financial performance, executive roster, or continuing website. On the available evidence, Intermountain Manufacturing Company should be catalogued as a defunct historical aircraft manufacturer whose principal significance lies in its revival of CallAir production and its brief development of the B-1 agricultural aircraft.
