seemed to be two types of stones: a flat
rectangular base piece with a carefully shaped stone
on top with a central slot and a possible spout at
both ends. They are about 18in x 12in. I saw a
worn top stone outside the museum, but no clues as
to how these stones operated.
never encountered anything like them before and have
been unable to find any information on the
internet. I wondered if anyone reading this knows
how they worked and what they milled.
guess is that a cylindrical runner stone revolved in
the top depression but there were none in the wreck.
