Early medieval silver equal-armed brooch. The brooch comprises an arched bow linking two wide, roughly-trapezoidal 'arms' with straight outer edges. These edges are decorated with a single incised bordering line inside of which is a row of double half-annulet stamps. The bow is undecorated. On the back is a single pin lug with a copper-alloy axis bar, a double-loop spring with chord and the stump of the pin. The remains of a separate catchplate is attached by solder. The brooch is covered with a thin layer of corrosion product from the copper-alloy pin mechanism.

Notes:

Equal-arm brooches developed on the Continent and are numerous finds there, particularly in the Elbe-Weser region (Bruns 2003, 1 and map 1; also discussed by Evison 1977, 127-147 and Hines 1984, 253-259). They are rarer in England, although their number is growing with metal-detected finds. The most elaborate types of equal-armed brooch are ornamented with chip-carved decoration, but simpler examples that are broadly comparable with the 'West Norfolk' find have been found in Brandon, Suffolk (Ashmolean Museum, 1992.103; Macgregor and Bolick 1993, no. 18.2), Norfolk (Ashmolean Museum, 1992.104, Macgregor and Bolick 1992, no. 18.3), Newnham, Cambridge (MAA Cambridge, 1892.FB, Hines 1984, fig. 5.8). These examples are decorated with punches along their terminal edges, but their bows are more elaborate. Most known examples are made from copper-alloy, but silver examples are known, for instance an elaborate fragment from the Nene Valley Area, Northamptonshire (PAS database DENO-21EE96; British Museum 2010,8026.1), and a far more comparable example, also largely plain but with stamped edges (albeit concentric circles), among a hoard from Binham, Norfolk (PAS database NMS-D18CC1). This form of brooch can be dated to the fifth century.
