This is the shortest answer I have ever seen in a Challenge, but it is correct and within the rules.
This beautiful monoplane was designed and built in 1914 by
Robert D. Bruce of Pittsburgh, Pa. Characteristic is the Taube-like wing and the almost bird-like construction of the rudder and elevator. the tail / rudder construction is probably unique for that time.
Robert Bruce also made an effort to mount the engine with a three-bladed propeller, which for that time was also very rare, probably by the effort that was needed to build a wooden three-bladed propeller (most were two- or four-bladed models). The propeller is given as a Paragon model. The engine fitted to this advanced machine was a 70 hp four-cylinder water-cooled engine.
The machine of Robert D. Bruce was patented on April 7, 1914 as Patent
D45550. The patent clearly gives the bird like construction of this machine. The construction of Bruce is here described as an
Air-navigation Vessel, an old term first used in US Patents in 1875 (Improvement in aerial vessels - Patent 168788), later fallen in disuse completely.
There is a small advertisement in Aeronautics October 15, 1914 (p.107) quoting:
WANTED - Party with $2.500 to take half interest in Airbirde Exhibition Co.: can book machine solid season 1915: will give same interest to flyer having 80-hp Gyro motor, or to manufacturer of financial responsibility who can assume the manufacturing license; will furnish the machine for affirmative tests. Robert D. Bruce, 338 Hastings St. Pittsburgh, Pa.
Obviously the Airbirde Exhibition Company was in need of financing.
