Part Cherokee,
I examined a few original Cherokee arrows in the Smithsonian in Washington D.C. a little over a year ago. The shafts were mostly split hickory, about 33- 35 inches long. Two of the arrows were made from shoots that had a pith in them...I'm assuming they were sourwood. But ALL the arrows had the Cherokee style two-feather type of fletching that several people have posted pics of. Also, the feathers appeared to have been put on with a twist to help them spin in flight. But the fletching was in rather poor shape, and some didn't have any feathers at all. They were all secured with sinew. The feathers were cropped quite low and were lower profile than the ones people have posted pictures of, but they are basically the same except for feather height. The fletching was wild turkey wing feathers and the arrows came from Cherokee, North Carolina, though there were no dates on the arrows that indicated when they were collected. Hope that helps!
