Who is the pot call surface source?
I use to hear if a guy named Chad Hutcherson or some like that use to sell slate, Glass and etc.
Stumpy on here if I remember right. Great ceramic calls. Here is a link to his profile. http://oldgobbler.com/Forum/index.php?action=profile;u=298

Stumpy is the man...
Most consistent products I have seen.
Stumpyglassman@yahoo.com is the best way to get with him.
He is also on FB.
Chad Hutcheson is his actual name.
