Description: | A complete copper-alloy lock pin. The lower portion of the lock pin is a sub-rectangular shaft which is rectangular in section. The shaft has file marks over its surface. The lower terminal has an oval perforation. At the upper portion of the lock plate and integral to the shaft is a circular head which has moulded sides, forming an off-centre waisted section, with an integral shallow, inverted conical above. The upper surface of the head is convex with a central conical with a low-relief pellet at the tip. The surface of the lock pin has a well developed mid grey/green patina. It measures 52.37mm long, 25.11mm diameter and weighs 38.6g.A similar lock pin is illustrated in Crummy (Crummy, N 1983 Colchester Archaeological Report 2: The Roman Small Finds from Excavations in Colchester 1971-9, Colchester Archaeological Trust) Nos 4142 & 4143). Crummy also states that copper-alloy lock pins are most likely to derive from small locks for boxes or cupboards and that 'the visible and sometimes the moving parts such as the lock-plate, bolt, tumblers and key were of copper alloy, while the internal parts such as casing were of iron. Larger locks fitted on doors would almost certainly have been made of iron for greater strength' (ibid, p. 123-4). The Colchester examples date to the mid 1st to 3rd centuries which probably applies to the recorded example.
