In between the Stout AT-2 and the Ford 4-AT, Stout built this hideous trimotor aircraft. Its flying qualities were as terrible as its looks. Ford had William Stout removed from the design office and moved on with the AT-4 which looked like a metal copy of the Fokker F.VII-3m. The sole 3-AT was destroyed in a factory fire.
