 The windmills comprise a steel frame and fan which turns to the wind between a bearing at the bottom and a swivel at the top, all supported by guy-wires.Along with another example in Jerilderie in the Riverina, the fully restored windmills are the only two known working examples in the world designed so their fan is contained and spins within the fully pivoting frame.There is a lookout at the top of Kelman Street, known as Gilbert's Lookout in honour of John Gilbert, a naturalist with Ludwig Leichhardt's 1844 expedition.
