It is now undergoing private restoration. This ironwork sign is set on top of the post from the old post mill which stood on Swafield Road, North Walsham and which was worked in conjunction with Swafield watermill. No picture is known of Thurlton tower mill in its working days, so the ironwork sign shows it with a dome-shaped roof but no sails. This sign shows an open trestle post mill. There was a tower corn mill in the village at Upton, but no record has been found of there having been a post mill in either village, though a miller at Upton is given in the 1802 Poll Book.
Sign shows a post mill with a square roundhouse with the body sitting squarely over it.
This figure is actually the Ordnance datum of the site, its height above sea level, recorded for the known sites of the county's corn mills. The tower corn mill at Walpole Highway is shown on this sign. The sign shows a drainage mill. The sign shows a tower mill as a West Norfolk drainage mill. The sign shows the front view of the tarred mill with white cap and four white sails.
