The ww1 wood propeller measures 47.25" x 4" x 2.25". This propeller is an authentic reproduction that was hand painted on each end, and made of wood brass hardware. This item can be hung vertically, horizontally or at an angle. Mounting hardware is included. Wood propellers used to be replaced as often as tires. Old ones were usually taken home, completed with a clock and hung over the mantel by mechanics, pilots and flight-crew. The typical ww1 flying ace was accustomed to wrecking a plane every now and then. For good luck he took the propeller home a turned it into a clock.
