The Wheels Go Round

This week's Mystery Artifact is a very useful little object.  Many settlers in Illinois would have never made it this far without it.  The object is forged metal consisting of a round, flat wheel with four spokes.  The wheel spins on a handle riveted to the center intersection of the spokes.  The handle is flat along the wheel's circumference, then rounds out and opens up to a loop at the end. 

As always, leave your guesses here or on our Facebook page, and come on in to see the artifact firsthand!
