Technical Observations: The patina is dark green with spots of light green and an underlying layer of red. A few small areas of the surface are well preserved, but most of the surface is covered with a slightly rough corrosion layer.
The thickness and shape of the cross-section vary throughout. The details of the shape were produced in the metal, probably prior to bending it into a circle. The four grooves near the button terminals were probably formed by hammering using an elongated punch.
