Probable Roman mount of cast copper-alloy. The object has a rather complicated shape, symmetrical along its longest axis, narrower at one end and flat in cross-section. The wider end has three large projecting knops: a trapezoidal one in the centre and a rounded one on either corner. From here to the narrow end and mirrored along both edges is a smaller rounded knop followed by a larger triangular projection, another small rounded knop and finally another triangular projection. The edges of these last triangles gradually curve around to join each other and form the narrow terminal of the object. There is a small amount of damage here and tiny bit of the edge has broken away. The break is worn.

There are two holes in the object, a sub-triangular one in the centre (c. 10x7mm) and an oval one at the narrow end (c. 11x6mm). Both are very worn around the edges. It seems possible that the oval hole served as a suspension loop and has ovalized through wear from a more circular starting point

A more precise identification of the object is elusive at present. Tentatively assigned a broad Roman date. c. 43-410 AD.
