This photo of Redcar mill is the only one that seems to be in general circulation, sadly no sails were present at this time.
Recently Ian Weber has suggested to me that the photo widely regarded to be Coatham Windmill could also be Redcar.
His suggestion is that a similar wall with buttresses at the bottom of the photo seems to still exist today ?
Whilst it does look very similar, the argument against this is the two white brick chimneys visible in the background of that same photo (a block of 8 and block of 4) which match those still to be seen on Station Road today.
Let us now turn out attention to a series of old etchings which show the windmills. If we’re looking west at the back of St Peters then the six sail mill is in Redcar to the right and the four sail mill, although appearing close is actually in the distance in Coatham.
This 1836 view east at the tower end of St Peters, shows the six sail mill near to the church as expected.
A similar view looking south-east from the seafront, again shows the six sail mill very clearly.
So what of the third windmill ?
It stood near Marsh House Farm at Warrenby and was destroyed by fire in 1815.
This windmill was built somewhere between 1861 and 1863 by George Burnett, the mill was 64ft tall with three storeys and had 4 sails which were apparently still in use until around 1915.
After this the mill fell into disuse and the upper stories were removed in 1960.
High Leven Mill dates from around 1750.
The windmill was converted to a house around 1966 -1968 (depending on your sources) and now operates as a B&B.
Coatham windmill was located on Station Road and parts of a substantial sandstone wall are still present to the rear, although again it may be nothing to do with the windmill.
Update 2013 : This old photo of the church on Station Road shows a structure behind that must be part of the Windmill, apparently used for observation during WW1.
Update 2015 : Ian Weber has also kindly pointed out it being shown in the back ground of this photo too.
This photo is believed to be the Coatham Windmill, which had 4 sails
