Description: | A complete cast copper-alloy lock pin of Roman date, AD 43-410. The lock pin is comprised of a rectangular sectioned shaft and wider circular terminal head at one end. The shaft has a width of 11.6mm and thickness of 5.9mm next to the circular terminal. This tapers to a width of 10.0mm and thickness of 3.9mm. The end of the shaft is angled diagonally so the length along one edge is 37.1mm increasing along the opposite edge to 39.0mm. A circular perforation, of 4.0mm diameter, is present 2.0mm in from the end of the shaft but is now filled with corrosion product making it barely visible. At the opposite end of the shaft the circular head expands from the shaft to a diameter of 24.8mm, flat on the shaft side and tapering to form a cone above for a length of 10.6mm. The surface of the cone is decorated with two incised grooves and a concave moulding which create concentric circles and creates a stepped appearance. The circular terminal then continues with a smooth surface for a length of 9.0mm, starting at a diameter of 12.7mm and tapering to a diameter of 9.2mm. The head terminates with a flattened bun-shaped knop of 15.0mm diameter and 7.4mm length. Between the knop and rest of the cone shaped terminal is a thin collar, 12.5mm diameter and 0.8mm length. This lock pin weighs 61.86g and has a total length of 67.4mm.See PAS record numbers WAW-D6B013, SUSS-CD79A1 & LON-B12BE6 for just a few examples of this type of artefact recorded on the database.See Crummy, N.
