I was reading a thread about making wingbone calls on another forum, and it occurred to me that, while I have seen many modern-made wingbone calls ranging from dead plain to scrimshawed and stained, I may have never seen an antique one (I think there may be a photo of one found in a bag in one of Madison Grant's books and I think that there is a picture of a single bone being used in one of the Foxfire books) nor have I ever run across a discussion of what is the PC way of joining the bones, number of bones used, etc.
Now I understand that 200-250 years ago people used their voice unassisted to imitate turkeys much more than today, and I think that they probably hunted turkeys much differently than we do today - using a call to locate flocks and then stalking into range instead of trying to entice a tom to the hunter's location. That may explain the relative lack of turkey calls. Still, it is curious that despite a great number of assertions that the wingbone call is of great antiquity,I haven't seen more originals.
The same is true with box calls. Mark Baker had an article in Muzzleloader once that included a discussion on turkey calls, and his source remarked that the earliest dated boxcall he had seen was 1803, and that it was unlikely that they predated 1790. I would also be curious to see if anyone has pictures of an early boxcall.
