"Look what I found"
It could even be older. A Enterprise #7 with a patent date of Oct 21, 1878. I have had and been using for 25 years. It has never failed to deliver a consistent grind. Has a thumb screw to adjust pressure on the burr plates. Tighten the screw till it locks up, loosen 45 degrees for expresso, 90 for drip and 135 degrees for FP. Once the wheel it turning, it tears thru the beans. A nice piece of history that still works great.
