The names stated above are very familiar. I know I have read them on HNI before and one of them may very well be the one who made the call for me.
I dug up some photos, in the last photo is the call that was made for me and was used in part of taking each of these birds.
Last year spring, my dad and my double.
My 2010 bird, may 22.
My dad's bird from May 25, 2010. The call is in his left hand. I was given the slate pot along with a wooden striker and a plexi glass type striker.
