Here we have an antique Model No. 2 cast iron single-wheel coffee grinder with wood handle, made by the  C.S. Bell Company in Hillsboro, Oregon. Nice collectible. Probably from the late 1800s. Measures about 18" tall x 16 inches long. Everything turns just fine, I would say its very likely that this grinder is fully functional, but I cannot say for sure since it is untested. Looks to be in very good overall condition for its age, as you can see from the photos. Don't hesitate to ask questions.
