Lincoln Sport

The first sport single-seater of note in the early 1920s was the Lincoln “Sport,” which was a biplane originall~ developed as a homebuilt by S.S. Swanson in 1923. It was put into limited production by the Lincoln Aircraft Co., of Lincoln, Nebraska, when Swanson became chief engineer there. The production model died for lack of a market because there were still plenty of cheap World War 1 surplus single seaters around for the sporting types. The Lincoln design was perpetuated as a homebuilt, however, when the plans were published in Modern Mechanics magazine in the early 1930s.

Lincoln Aircraft Company Inc / Lincoln-Page Aircraft Co / Nebraska Aircraft Co

Ray A. Page established Nebraska Aircraft Corporation at Lincoln, Nebraska, during the First World War, and was a builder of the Lincoln Standard biplane, and also built aircraft under subcontract to the U.S. government.
Began construction, in 1922, of the five-seat Air Coach. Between 1923 and 1925 offered the Lincoln-Standard Tourabout, a three-seat rework of the Standard J.1 of 1916. Also produced the Sport Lightweight biplane. Page acquired the rights to the New Swallow and redesigned this as the three-seater Lincoln-Page LP-3 in 1928, an attempt to catch up with developments in light aircraft design. In 1929 produced a two-seat trainer known as the Lincoln-Page Trainer.
Lincoln Aircraft Company Inc was the official name of Lincoln-Page from 1929, but both names used indiscriminately.
The last design was the parasolwing Lincoln Playboy of 1931. Firm was by then the Lincoln Airplane and Flying School.
