This early style propeller is laminate in construction and features the distinct cutout for use on the Curtiss flying boat. The wooden surfaces have maroon varnish and white paint applied with the tips of the propeller sheathed in brass which has been riveted on. While most of the markings on the propeller are obscured, a visible "U(anchor)S" marking is clearly legible. The propeller measures 104 1/4". The Curtiss flying boat is seen by many as the grandfather of commercial aviation thanks to its capability to fly across the Atlantic and ability to carry cargo. Though the Curtiss flying boats purchased by the United States did not take part in the war effort in Europe, it was heavily used to patrol coastal waters for possible U-boats. These U.S. Navy propellers are seldom seen, as reportedly only 20 Curtiss flying boats were procured by the U.S. Navy in total.
