after contacting the Roberts Brothers turkey calls sights many times it appears all the numbers have changed so I am assuming they are out of business. anyways i know that i have some custom call makers on here. I am looking for someone that can make some custom strikers with the conditioning stone attached to the top like the roberts brothers. i absolutely love those things. I will pay fairly for them! i want 3-4 in different kinds of woods. please comment or pm me if you can.
