I also have to hunt third week of October, Calls still work, just not quite as well as they do in September.
As to pics of the call, sorry, it's at camp.
The loud call we use at night, is a can that's a little longer than usual. It's a can that a bottle of Baccardi rum comes in up here. It's about a foot long, and about three inches across. The shoe lace, is a piece of leather, and we soak it in water before use. Grip it tightly and give a short jerk on the string, forcing the wet leather to slide between your fingers. Some guys are better at using it than others. One of our guys can really make it squawk.
We have others made from Tomato juice cans. They also work, just not quite so loud.
