Hello, have anybody seen this type of primitive predator call before? I believe it is very old. Origin unknown. Maybe you would like to make your own in just minutes (very easy) and try it out for me this season? Have a look at the pictures and full description for both making and using it on youtube : http://www.youtube.com/watch?v=vL5nsELPkIo or search youtube for stone age predator call . Please let me know if you have any luck with it. Im posting it on youtube so that it will not be forgotten among hunters. It has been passed from generation to generation and finally to me. Now, thanks to the internet, even to you. Good luck.
