1920's Hamilton Standard Menasco Ground Adjustable Airplane Propeller Blades

An exceptionally rare pair of 1920's Hamilton Standard ground adjustable airplane propeller blades. These propellers were produced in very very small numbers. This is the only set we have ever come across. This propeller was used on an early Menasco engine.  The Menasco engine was used on the Northrop Experimental Avion EX-1 (X-216H) Tractor Airplane.
