I'm looking for information regarding a "hambone" duck call made by C.H. Amaden of Lonoke, AR (GO HOGS!). I came across this one in a second-hand shop. It was still in its original box with 2 reeds and appears to have never been used. In the box was a price list dated 1978. Does any one have any information on the craftsman or these duck calls. Ive had it for about 24 hours and have had 2 people at work offer to buy it. I don't really want to sell it but it has peeked my curiousity. It is walnut and has a transparent and green label. Any information would be helpful. Thank you.
