Technical Observations: The patina is a rough and pitted green with reddish-brown and black corrosion over a pitted, dull black surface; some areas of bare metal are exposed. The spring, catchplate, and pin are missing. On the underside of the fibula, a thickened section of metal forms an X-shape and probably served as reinforcement. No tool marks can be seen on the poorly preserved surface.
