A corroded and incomplete cast copper-alloy Colchester brooch dating to the late Iron Age to early Roman period, c. 25-65 AD. A one-piece example with a broken and now vestigial rearward facing hook at the top of the head (L.: 2.9mm). This hook would have held the external chord of the spring; this latter, along with the pin, broken just below the head, is now missing. Below the hook there are two flat wings which survive bent and abraded (W. across wings: 17.2mm). The bow is sub-oval in cross-section. It tapers from a maximum width of c. 6.5mm to less than 1.4mm at the catchplate end, where it now forms a sharp point. The catchplate itself is highly abraded: a slight line only remains. The artefact has corroded to a red-brown colour with a patch of green bronze disease affecting the upper bow.
