Wolverine Aeronautic Co

The Wolverine Aeronautic Co, Albion MI., USA circa 1911 was a supplier of home-builders’ kits and materials. They featured two open cockpit biplane models with 25hp (span: 26’0″) and 30hp (span: 30’0″), powered by Wolverine’s own-brand motor.

One machine was reported by Aeronautics to have been built for the Chinese revolutionary party, representatives of which watched it in demonstration at Hempstead, but that “apparently the idea of using aeroplanes was given up at the time.”
