An incomplete cast copper-alloy catch-piece from an Early-Medieval/Anglo_Saxon wrist clasp of Hines' Form B12. It is missing one end due to old breaks and has been slightly bent due to post-depositional damage. The object is formed from a straight rectangular bar that is rectangular in section and has raised square panels at the surviving end and at the centre. On the outer edge of the end panel is an integrally cast, flattened semi-circular sewing loop or lug that has a central circular perforation and has suffered from post-depositional damage resulting in it being slightly flattened against the bar. From the outer edge of the central panel projects an integrally cast spiggot that has a narrow neck before expanding to a semi-circular terminal. On the inner edge of the central panel is a flat, rectangular catch-piece with central oval shaped perforation. The back face of the object is flat and undecorated, all surfaces retaining a dark brown patina that is worn in places. It measures 22.59mm in surviving (bent) length, 20.86mm in width (8.21mm in width at bar), 2.22mm in thickness, and weighs 3.65g.

This is one incomplete half of an Anglo-Saxon wrist clasp, the loop indicating it is the catch rather than hook piece. The use of a straight bar with integrally cast sewing lugs, spiggot and catch piece indicates that this belongs to Hines' Form B12, which is datable to the late-5th to 6th centuries AD (Hines, 1993: 46-49; see West, 1998: no. 118.4 for a similar example classed as Hines B14a).
