Technical Observations: The patina is green with areas of brown. There is a break on one side above the crossbar holes. The surface is well preserved.
The main section was cast as a single unit. The thin vertical arms have hammer marks on much of the surface. They were cold worked to a thin, uniform dimension after casting. This would have strengthened this relatively delicate portion of the casting. The holes, which are very precise and show few artifacts of the drilling process, were made after the flat elements were hammered. The heavy wire crossbars show many hammer marks and were probably given most of their current dimension and shape by hammering. The slight projection at the bottom of the handle could be related to an attachment, but it has a smooth rather than broken texture. It could also be an appendage left from the casting process.
