An incomplete copper-alloy Roman brooch of the Colchester Derivative double lug type, dating to AD 43-100. The head has two wings with a C-shaped profile; they house a copper-alloy spring, which is coiled around an iron axis bar. The axis bar and a fragment of the chord are held by a double lug at the centre of the back of the head. The front face of the wings have a transverse groove at the outer end. The bow is oval in cross-section and tapers towards the broken foot. The spring is moderately worn and stained by iron corrosion products. The surfaces are abraded.
