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 spring mechanism and the pin are missing. The wings are semi-cylindrical and there is a faint single vertical groove on the outer edge. The bow is undecorated, D-shaped in section and is damaged between the foot and the catchplate.
