Description: | An incomplete cast copper-alloy Colchester one-piece brooch (AD 20-70). The brooch has a spring of eight turns with an external chord which is 1.5mm in diameter. Viewed from the rear, the spring emerges from the underside of the head, spirals four turns to the right, returns 180ยบ over the top through an overhead chord hook, spirals four turns to the right and when complete would have extended to form a pin. However, the pin is missing due to an abraded break. The small wings at the head of the brooch, situated below the chord, partially obscure the front of the spring. The bow curves evenly in side profile. It tapers evenly from the top towards the bottom and is 'D'-shaped in cross-section, flat at the rear. The width at the top of the bow is 6.1mm and at the bottom the width is 0.4mm. Its maximum thickness is 1.7mm. The catch-plate is centrally situated on the median centre-line and is 'D'-shaped in side profile. However, some of it, including the curled-over part that secured the pin is missing. The front of the bow appears to have two vertical narrow grooves near the top that merge together about half way down. This brooch has no patina and is partially covered with loose light green copper-alloy corrosion products. The surface of the metal, where visible, is a dull matt brown colour. Length: 51.3mm; overall width: 19.6mm. Weight: 6.58g.
