Description: | A complete cast copper-alloy lock pin. The lower portion of the lock pin is a sub-rectangular shaft which tapers and is heavily abraded. This may not be intentional tapering as lock pins are usually perforated at the terminal. The upper portion of the locak plate and integral to the shaft is a circular head which has a slightly convex surface with a conical shaped centre. The base of the conical is decorated with a low-relief ring. Between the shaft and the head there is a narrowed circular disc. The surface of the lock pin has a well developed mid grey/green patina. It measures 40.41mm long, 19.75mm diameter and weighs 14.2g. 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.
