This is a Burlap Sack. It is a nice piece that was probably used as either a back pack that carried supplies or something on a horse drawn carriage. It still smells like it has been around horses or livestock. It is quite large as you can see with the cd that I used for size comparison. It is made up of Burlap material and has 3 metal hinges which hold the thick braided rope in place. I have yet to spot it in an episode but I am sure I will.
