mill stone rotary quern

this is a short video of a quern stone that i picked up at a yard sale .... it is shaped from solid granite .. and i would estimate its age at somewhere round the 1840s.. at about that time it was illegal to own one!-- you were expected to buy your flour from the company mill ,,(thirlage ) and company men would break peoples querns to effect the monopoly ... it is hard to find any left in countrys like scotland just on a green organic note fresh milled grain contains the wheat germ ... whereas factory produced flour the wheat germ , part is removed (the most healthy part ).. because it becomes rancid after 2 or three days ... therefore fresh milled grain is far more healthy p.s. you woudnt want a mill stone round your neck
