The Post mill stood clos to the site of the existing house "Milldene" on the north side of Ransom Road, 190 yards SW of the tower mill (known as Tiptree Windmill-see 8199). Together these mills, with dwelling houses adjoining, comprised one estate. Reconstructed in 1775 it had one pair of French stones and a new flour mill and dwelling house. Measuring 18feet long by 10 feet wide, when put up for sale it was reported to have 2 pairs of French stones, a flour mill and a brick roundhouse.<1>Chapman and Andre's survey predated the erection of the Tower mill(8199) so records the Post Mill only.<2>Greenwood (1825) shows both mills, but places the Post Mill at some distance to the NW of the actual site.
The Post mill is not shown on the first ed. (1874/5) OS map so it must have been demolished by then.<1>
