I just tried my hand at making a wingbone call today, matter of fact, I made two. I had done some horse trading to get one for a pattern, mine turned out better than the one I traded for. Jesseshuntingpage, is the source I used for tips on making them. I bleached mine a little longer than he calls for and they came out looking like ivory. Very anxious to try em next year on a longbeard. They sound pretty good too. On Jesse's page, he says hens wing bones make the best call, because the bones are smaller and thinner walls. Made mine from a jake a friend got. If you try it, gotta have a Dremel tool, makes short work of the fitting of the bones together. Good luck
Stay calm and pick a spot
