Research leads me to believe that this mortar was used for grinding grain and hemp seed. 21" tall and measures almost 7" in diameter. The wood is 1 think. The letter "R" is carved into the wood on one side.
There are insect holes and dings on the mortar, mostly near the base. The forged cast iron pestle measures 31-1/2 tall, and I'm including the cast iron forged ring for hanging.
The mortar and pestle together stand 35-1/2 tall. The item "Antique Large MORTAR & PESTLE, Hand Turned Wood, Forged Cast Iron, Grain, 21 Tall" is in sale since Sunday, May 6, 2018. This item is in the category "Antiques\Science & Medicine (Pre-1930)\Apothecary & Pharmaceutical\Mortar & Pestles".
