Scale: Unknown. A model of a Spencer's proposed anchor (1820-1822). The model is made in wood with a painted lead ring (oxidised) and has been painted a uniform black. The shank is square in section and tapers out in a triangular shape towards the crown of the anchor. There is a shoulder just below where the ring passes through the top of the shank. About halfway down the shank it widens to form a triangular-shaped crown through which a large circular bolt passes with the pivoting flukes passing through the aperture in the shank. There is one large triangular-shaped fluke and a smaller one inside that which is square in shape with a small hole drilled through just above the pivoting bolt. The pivoting bolt was probably used for tripping the anchor when in use. The flukes themselves are able to pass through the shank and out on either side also allowing them to be stowed flat on board ship. The remains of one paper label showing the number: '6' is applied to the shank.
