Ultra-rare and highly sought-after 1919 Boyle-Dayton Aero Gas Pump. This phenomenal showpiece has been restored to the highest of standards with no expenses spared by McLaren Classic Restorations. This Boyle-Dayton model was ahead of its time in engineering. It had an air-assisted ram at the top to aid the operator in pumping the massive 5 gallons of gasoline per stroke. Size: 19'x119'x19'
