Ok here is my question. Had a guy call he is a local trapper and he caught a huge beaver. 72 inches as a matter of fact. He round skinned him and air dried the pelt. He wants to get it tanned as a wall hanger. I understand and have tanned deer and elk backhides but not a beaver. I have all the trubond stuff I need its a great product. What would you charge him is my question?
