Native Tin Lizzy Black Anodized Aluminum/Glass Pot Turkey Call - The NEW TIN LIZZY is a black anodized aluminum face over a glass soundboard in our smaller 3.25in walnut pot base. This thing runs light and easy cranking out outstanding turkey sounds. It excels in purrs and clucks with a strong steady yelp with light pressures. They ensure that their aluminum calls are simple and smooth to operate. Native recommends maintaining the surface with 80 grit sandpaper or a medium grey grit sharpening stone.
