English: A worn early Medieval copper-alloy trefoil brooch, measuring 51mm by 54mm in size with one complete and two incomplete arms, the incomplete arms are missing their terminals due to old breaks and wear. Each arm is rectangular in shape and c19.6mm in width, the complete example has a rounded terminal end. The front face of is decorated elaborately with interlaced knot work with a raised knot motif in the centre of the front face. There are tiny traces of possible gilding on the front face too. On the reverse there is a corroded double pin loop, with the probable remains of a corroded iron pin within it, projecting from the centre of the terminal of one arm, projecting from the terminal of the other arms there is a single loop, again with corroded iron within it and a fragment of a possible third projection, the nature of which is no longer clear. It therefore seems that this brooch has a pin loop, possible catch plate fragment and another possible chain loop. It therefore could have functioned as a brooch with a chain attached to it. Trefoil brooch fragments are known from both Norfolk and Suffolk, a complete example has been found in Wymondham, Norfolk (see NMS-10A1E1), another Suffolk example from Long Melford is also known (see SF-C7C9B1). This example may have continental and possibly Scandinavian origins and is most likely to be circa 9th century in date.

Jane Kershaw having seem images of this brooch believes that it belongs to Maixner's type F 3.1, a small Scandinavian series represented by only a handful of finds from eastern Sweden, including a brooch from a late-ninth or early-tenth century grave from Birka.
