Scale: Unknown. A model of Hall's patent anchor made entirely of brass and nickel plate. The shank is rectangular in section and tapers towards the top. The stock is a flattened V-shape in profile and narrows towards the ends. Two circular apertures are inset at either end of the stock. The stock is held in position by a wedge. At the top of the shank is a D-ring shackle that swivels on a round headed rivet. On two sides of the shank are inscriptions: 'Halls patent anchor Co Limited' and '26 George St Sheffield'. The crown has a large rectangular aperture through which the base of the shank can be seen. The shank pivots on the crown through an arc of about 75 degrees. Two flat arms sweep up from the crown and extend upwards terminating in a pair of arrow shaped flukes.
