Saw this impressive working replica of the original mill this past Saturday. It was built from 2005 to ‘07.
The wind engine drives three reciprocal sawing stations at once via a crankshaft.

Plenty of photos here. and here.

The original was built in 1680 and stood for almost 300 years. Fortunately a man named Anton Sipman had the foresight (and/or the commission) to make detailed scale drawings of all the critical parts before it was demolished in 1942.

One interesting detail the photos don’t show is that they used 12 different species of wood from at least four continents to build the thing. The large timbers are resilient long leaf pine from the US. Gear teeth and bearings are made of denser and more exotic species.
 
Here is a detail of the turbine’s gear and both braking mechanisms. The toothed rack in the foreground left locks the turbine after it is been stopped by the pressure pads behind it.

The reed thatch is also visible.
