Wilson Atomatoys

Wilson Automatoys is a pre-War company. Its only known product is the Giddyup Buttercup.

Appearances
Wilson Automatoys is mentioned in Fallout 3 and the Fallout: New Vegas add-on Lonesome Road.

Their corporate headquarters and one of their factories make an appearance in Fallout 4, though the name has been changed to Wilson Atomatoys, likely implying they are nuclear powered to some degree.

Behind the scenes
While this company naturally went under after the Great War, their legacy was continued by the Mothership Zeta aliens. This is seen aboard their mothership, as the aliens have built entire production lines with the specific intent of creating Wilson Automatoy's Giddyup Buttercup toy.
