Gibson was created out of the Gibson corporation in Seattl, Washington. Wilbur Gibson opened a tractor manufacturing facility in Longmont, Colorado. Several tractor models were built before the company was sold to Helene Curtis Industries in 1952. Western American Industries resumed production in the Gibson factory from 1953 to 1958 before closing.
