Technical Observations: The patina is a superficial black with bright metal visible below. The surface is deeply pitted and irregular due to corrosion. The corrosion products appear to have been completely stripped away using an electrolytic process. The current black surface is modern.
The attachment is a solid cast. Except for faint lines on the hooves, almost no decorative detail has survived. No evidence of cold working has survived.
