Technical Observations: The patina is dark green and gray, and the object is a solid cast. The rectangular legs were added to the more rounded shape of the body, presumably in the wax model. The body could have been hand formed in wax or cast in a mold and pinched to a thinner dimension at the tail. There is no evidence of mold lines. The 3-mm hole at the top of the back is a casting flaw. The gray color of much of the corrosion products and the white color of the drilled sample are a result of the high lead content of the alloy.
