Scale: Unknown. A model of a Spencer's proposed anchor (1820-1822). The model is made in wood with a lead ring and is painted a uniform black. The shank is square in section with rounded edges ending in a flat and rectangular section with a large, circular fitting holding the large pivoting arms and flukes in place with a circular bolt. At the top of the shank are shoulders either side just below the lead ring. The palms are secured by three large rivets to the arms (one detached) and are flat and almost circular in shape. At the crown of the arm is a small lug with a hole through which a tripping rope could be attached. There are three paper labels attached to the shank of the model which read: 'WS September 1822', '1?', 'Anchor, adapted for securing in deep anchorage?'.
