The handwritten contract between the millwrights and the Reckitt brothers, describing how the windmill will be constructed, is reproduced below. The original documents survive in the ownership of the Waterfield family.
The partnership of Norman and Smithson was responsible for building several fine tower mills in Lincolnshire and Yorkshire in the 19th century. Maud Foster Windmill is now the only complete survivor. The millwrights' quoted price was twelve hundred pounds, excluding the brickwork - a princely sum even in those days, but thoroughly justified because the mill was clearly built to last!
