The power plant is the Pratt and Whitney "Hornet" engine with 525hp. The Metalplane was manufactured by Hamilton Metalplane Company in Milwaukee, Wisconsin, a division of Boeing Airplane Company, Seattle, Washington. The Hamilton Metalplane was rebuilt and restored to its original condition by Jack Lysdale. Restoration started in 1972 and completed in 1975, after which it was displayed at Oshkosh and then taken to the 5th National Fly-in Antique Airplane Association and Air Power museum in Blakesburg, Iowa. The Hamilton was awarded five trophies, one of which was the AAA Grand National Champion award. Renovation included extensive re-skinning of the fuselage, wings and a substantial portion of the control surfaces. New gas and oil tanks, landing gear was magnafluxed and rebushed as needed, new windows and interior were installed. Seats were handcrafted with new caning and leather.
