Here's what an an original Greenwell's Glory looked like if anyone is curious. What struck me on this was how real the wings look! The original Henryville Special used to use red silk for the body that, when wet, would change to a ruddy brown color. If you look at an original, the color is like Pearsall's cardinal silk. Ernest Schwiebert in his Trout books, claimed to be the one that changed the body color to olive. The wings didn't look much like mallard either, but more like green winged teal.
