Fight to save Grimsby windmill labelled 'at risk' by Historic England
Volunteers have called for support to save a 140-year-old windmill labelled "at risk" by Historic England.
Waltham Windmill, in Lincolnshire, was a feat of engineering at the time it was built in the 1880s.
The former flour mill has been run as a working museum since the 1980s, telling the story of its agricultural past and role as a lookout post during World War Two.
Until recently it milled once a month, its six sails powered by the wind coming off the North Sea.
But decades of exposure to the elements have caused rainwater damage.
Peter Kingsford, a volunteer at the Waltham Windmill Preservation Society, said: "I think in most of these lovely old things - people can take them a bit for granted.
"We need to make an awareness that they are extremely vulnerable and it is a case of use it or lose it."
The site is one of 21 in Lincolnshire deemed "at risk" by Historic England. The medieval Hussey Tower in Boston and some timber-framed buildings on Lincoln's Steep Hill are also on the register.
In August the windmill's 16-tonne cap was removed for maintenance work, allowing volunteers to see the design up close.
Jane Holt, an architect for Historic England, said: "You get it down on the ground and you realise how clever the whole design is - the sales are curved, the little shades on the sails, they move.
"We forget how clever our forefathers were just using what they had."
A £63,000 grant has funded initial repair work, but the full extent of the problems mean a complete fix is likely to be much more expensive.
However, the volunteers believe further support could see the sails turning again by Easter.
