This weathervane was made by Leslie Williams in October 1959 and was acquired by the Powerhouse Museum the following year. An alternative name for a weathervane is a weather-cock because of the image of a rooster that was placed on top of the vane's spoke. An arrow also rotated on the spoke which when blown gave a visual indicator of the direction the wind was blowing from.
This particular object is probably modelled on a portable wind vane but looks to be an ornamental version which was displayed indoors. It is significant as an example of locally made Australian brass work.
