Mauser check out http://www.brooksidegamecalls.com/ they are a PA company and they have all the parts and pieces to make your own pot call, or just about any other type of call for that matter. They also have the ability to lazer engrave for you too. I have some friends who have bought off of this guy and they are very happy. He is based out of the area where I grew up. I haven't used him yet but everything I have heard is positive.
