> I have been working on a historic Grist Mill (corn grinding) site for
> about seven years now. I have never found an accurate drawing of an
> overshot waterwheel showing all the working components. At one point
> in time the mill was converted into a horizontal water wheel. I have
> several blades from the horizontal wheel which seems to indicate it
> was an enclosed wheel. No proof!! Date of the mill is 1835-38.

> mill.All guidance will be appreciated.
