by Yorkshire sash windows with brick segmental heads. Above the taking-in doors is a timber-planked and gabled lucam on timber brackets. Equipment The mill retains its original floor beams and mill machinery from 1819 by millwrights Norman and Smithson of Hull. The mill has three sets of grinding stones and is in working order. The mill has five instead of the more usual four patent sails, the shutters of which are now at Wrawby post mill. An unusual feature is the weather beam (or 'rode balk') which is made of cast iron, probably replacing the original wooden one. The brake wheel is a wooden clasp-arm type with an iron tooth ring and wooden brake. The wallower is also made of iron with a wooden friction drive to the sackhoist. The dust floor is more spacious than is often found in Lincolnshire and is lit by windows. Three pairs of grinding stones, two grey and one French, survive on the fourth floor with vats, spouts etc. all intact. The great spur wheel is made of iron, as is the upright shaft. The stone nuts have wooden cogs, as usual. The spout floor gives access to the reefing stage and contains a fine governor which controls all three pairs of stones. The bridge trees are made of iron and are Y-shaped with integral bridging boxes.
