Based on Swanson W-15 design, the 1934 Swanson-Fahlin SF-1 was a two-place cabin, high-wing monoplane, powered by an 85hp Pobjoy R engine. It first flew in April 1934, registered NX271Y c/n 1.
It was repowered c.1937 with an 85hp Continental A-85.
Disposition after c.1940 is uncertain, reportedly was stored in a hangar on a field taken over by the military, who consigned it to the scrap pile. Despite many references to a trio of Swanson and Fahlin-designed planes built by Nicholas-Beazley Co, only the SF-1 and SF-2 were built at the N-B plant, and those by Swen Swanson in rented space.
