Silver brooch fragment. The identification of the material has been disputed by the finder. Kevin Leahy therefore kindly re-examined the object under a microscope, and comments as follows: 'The fracture suggests that this piece is copper alloy'. The record has therefore been amended, with the silver surface appearance now considered as plating.
Cast bow from a small bow brooch, possibly Mackreth type Almgren 16. A straight-sided bow with a central longitudinal ridge and with grooved borders; neatly cross-cut horizontally and diagonally at its lower end. The top is constricted and curves forward; a simple spring is presumably lost from above this site.
