Enterprise double wheel cast iron coffee mill patented July 12,1898 No. 12

Found in the 1950's in an old store in Wyoming. It was in a packing box and had never been opened or used. My grandfather was given it as a gift from the store owner whose was selling his store. He kept it in the box until 19755, when he unpacked it and displayed it in his basement. I inherited it 17 years ago and have also had it displayed on top of a large whiskey barrel.
