This is such an exciting find! I think you could actually grind coffee beans in this miniature grinder. The grinding part and front of drawer are made of cast iron and are heavy. Notice from my photos the detailing on the cast iron. Also do pay attention to the hand carved hole that the ground coffee would drop into. Including the grinder apparatus this piece is 3 inches tall by 2 1/2 inches wide. Grinder turns freely. I am not sure if this was possibly made as a salesman's sample, but it is certainly nice enough to be one. Do note that there is wear to the wood. This is just a great accessory for any early doll-cloth, china or even bisque.
