Does anyone recognize this grinder? A handle on the rear turns a series of gears to get speed out of the grinding rock that measures 1-3/4 inches wide and 5 inches in diameter (it could have been as wide as 6 inches when the rock was new). The overall height of the grinder in the “down” position is 7-1/2 inches. When you push down the handle coming out of the left side with your left hand, the grinding rock raises to 9-1/2 inches. I am grateful for any assistance.
