An incomplete Colchester two-piece bow brooch of the early Roman period.
It is of the type that has a double-pierced lug for the spring mechanism, the lower perforation to hold the axis bar of the spring, and the upper one to secure its chord. The chord survives but the spring mechanism and the pin are missing. The wings are flat and decorated with an oblique and transverse groove. The triangular-section bow tapers to a blunt foot, and has decoration consisting of a longitudinal median groove with longitudinal grooves on the outer edges. The back of the brooch has a solid triangular catchplate.
