Drainage Windmill

These kind of windmills were used a lot to drain land, or so called 'polders'.

Some polders even needed three or more of these windmills in line, because one windmill on it's own was only able to pump out about one metre of water.

One of these series of mills can be found in the Schermer, pretty close to Zaandam.

Measurements: 6,5 x 7,5 x 8 centimeters (w x d x h, excluding wings).
