For $4K, I'll can personally carve you an exact duplicate of a 1903 Wright Brothers propeller... I've done it before, I could do it again.
TL;DR
A side note, my brother and I, homeboys from Dayton Ohio, helped build and fly a 1903 WB Flyer for the 100th year anniversary of the invention of flight for Dayton's centennial of flight Celebration back in 2003. I helped build 3 WB Flyers while I worked for the Wright Brothers Airplane Company, a historical forensic exploration of the invention of controlled, sustained flight. The company went to schools and gave historic static displays of Wright Brothers aircraft that we built and tried to fly, the same way the original Brothers did. I built parts of the static 1903 display aircraft, while my brother worked on the flying bird, building the entire powertrain that was used to fly it. We had a replica WB engine, but chose instead to try and fly using a twin cylinder 25 horse power Briggs and Stratton due to the outright extreme fire hazzard danger the original engine design posed. The power plant weighed the same as the original motor and provided 12 bhp to the props, and was the only engine the three pilots agreed to try and fly with based on reliability, safety and the lack of inherent propensity to spontaneously combust while operating. I carved a pair of props for the display bird, the exact same way Wilber did using hand tools and a draw knife. The ribs for the aircraft were assembled by the children under our supervision, and when they were finished with it, they signed it. They made tiny replica ribs to take home, all made the exact same way the big rib was made. So every time we gave a demo, we got a finished rib or two or three depending on the size of the class. The rest of the bird we made, and let me tell you, there is a lot to do. Of all the teams across America that built and tried to fly a replica In 2003, our bird was the only one that actually flew. And we determined why all the other teams failed, and why the Wright Brothers succeeded. Cold. The 1903 flyer loves to fly in thick cold air, and when we got ours to fly, the morning we finally flew, the temperature was 10 degrees Fahrenheit in Dayton, the same As Kittyhawk was the morning in December in 1903. It makes the props more efficient, and the wings more efficient. This allowed it to overcome ground effects that they later learned about when they tried to fly in Dayton after they returned and built their next aircraft. You need the launch tower and drop weight to get the aircraft airspeed above ground effects when temperatures are not freezing and you don't have a constant 50mph headwind like Kittyhawk did.
