Mill has single-sided cloth-spread common sails.

This is a very derelict mill, without sails, but it has its internal economy complete. The tower and gambrel cap were shingled, the tower was 41 ft. high, 22 ft. 3 in. across the base, and the cap circle was 17 ft. 8 in. diameter. The most unusual feature was the winding gear; this was worked by two winch bollards fixed in braces at dust floor level with mortises for capstan bars. There were two wooden pulleys, fixed in sheaves to the curb and opposite to each other, and fourteen removable wooden "anchors" in slots in the cap circle. A rope was made fast to one of these, passed round one of the pulleys and down to a bollard on to which it was wound, using a capstan bar. The brake wheel was behind the lantern wallower and braced to the 17 in. square windshaft the neck and tail bearings of which were of granite. The 18 in. octagonal upright shaft carried a clasp-arm spur-wheel driving lantern nuts. Two underdrift granite stones, one of 39 in., the other of 50 in. diameter were mounted on a low plinth on the first floor and had stiff rynds. The ratio of the dricv was 56 : 22 and 41 : 13.
