Scale: 1:12. A model of sea mine on its wheeled sinker. The model is constructed of metal, either welded or bolted together with its constituent parts, the whole of which is mounted on metal rails on a simulated wooden deck. The egg shaped mine is fitted with a number of conical triggers and a pair of bolted circular access plates at the top and bottom. It is connected to its sinker by a length of chain and wire which is housed in a rubber sleeve. The cube shaped sinker is complete with removable access panels and a mechanism for releasing the mine when the sinker reaches a certain depth.
