A Post Mill refers to a mill where generally the upper superstructure of the mill rotates. The upper part generally (but not always) contains all the milling mechanisms.
Post Mills
Post mills are the earliest type of European Windmills – dating back to the 1100’s.
Logically it is quite a weird design in terms of both functionality, complexity and durability – due the large above ground surface area and the fact they were mounted on a single post early Post Mill were prone to blowing over in high winds! As the design developed however, they must have been fairly functional as their design and use persisted into the 18-19th centuries.
Post Mills went through various stages of development - they started when the mill was mounted on a trestle, so it could be rotated into the wind. Rotation was usually carried out via a post that stuck out at the back.
The next development stage was when the trestles were buried for greater stability. As mills next grew larger, instead of burying the trestles, the area around the trestles was built in – this provided useful storage space.
Up to this stage all the mechanisms were housed in the upper or rotating portion.
Finally a lot of post mills were placed on a short axle.
Hollow Post Mills
With the lower part of the mills now enclosed, one of the next developments was to bore out the main post to take a drive shaft, which then enabled the milling machinery to be housed in the base. Cavier Mills are similar to Hollow Post Mills.
Paltrok Mills
These mills were used specifically to saw wood. The design differs from the Post Mill in that the WHOLE mill building rotates – there is a short axle or centre post, but Paltrok Mills in addition also rest on a solid brick base, on which there are sets of rollers to assist with rotation. These rotating structures include now not only the Mill itself and mechanisms, but also the actual saw mill workshop and wood stock as well - so the weight is considerable. These mills are confined to the Netherland and Germany and visually they look like a mill on a rectangular building. Visually it is not apparent that the whole structure is capable of rotating.
Composite Mills
Lastly these mills look like Post Mills, but the body does not turn or revolve.
-----------------------------------------------------------------------------
So what type of mill is the model?
Quite honestly I do not know! It lacks the post used to turn it, but this may just be an error. The base certainly looks like the filled in trestle shape used by Post Mills though. Or it may just be representative of a Composite Mill.
But of course there is also then artistic licence - either way it is a nice little model.
The Model
I became aware of this model after reading a post here by John Wagenseil. Check out the link above for details of the models John found.

Doug (SCEtoAUX) also made this model full size (about the same time I did) and it turned out really nicely! Have a look here at Doug’s model – same thread as above, but here’s the link direct to Doug’s post.

It appealed to me as a relatively quick build, so I downloaded it and then adjusted it a bit..............
