Here is a call i was hanging on to but decided to give it up. I'd rather someone use it then sit in the shop. This call is unique, there is no sound holes drilled at all. The sound comes from worm damage to the wood. Its a great sounding call, smooth and seductive. Its a spalted maple slate over glass. $40 plus shipping
