A Late Iron Age/early Roman (AD20-80) copper-alloy Colchester two-piece brooch, incompletein so far as it is missing the elements of its catch-plate, and much of its pin. The wings are short, flat and rectangular. Behind the wings is a hook that curves upwards to retain the axis bar, and, above this, an integral hook curved back on itself to retain the chord. The spring mechanism survives intact, around its axis bar, the chord retained within the rearward hook. There are two coils to each side; on one side the innermost coil develops into the pin which has been truncated after only c. 13.8mm. No decoration is visible on the bow which narrows towards the tip. The bow has a sub-circular cross-section, with flat upper and lower surfaces and rounded sides. It rises from the head before descending more gradually from its highest point; the head and tip are in the same plane. However, the angle at the highest point is not smooth and suggests that the brooch has been squashed post-use. The catch-plate is openwork with two rectangular perforations. Part of the fold has been lost above one of the perforations at a natural weak point. The catch-plate has a web 19.9mm long. The foot of the brooch has been bent to one side following old damage.

The brooch measures 48.1mm long by 15.7mm maximum width by 4.0mm thick at the bow. It attains a height of 21.8mm. It weighs 8.02g. It has a mid-green patina over a red-brown metal.
