Made this one out of some sweet Macassar Ebony got the urge from looking at Shannon's latest push pin caller. Since I am having such a hard time finding 1 inch outside diameter brass thin wall at a price that I could afford to make these and sell them cheap enough for hunters to use, this one has an aluminum insert with a buckeye burl stabilized lip rest on it. Sounds great.....headed to the classies....thanks pappy
