Technical Observations: The patina is green with spots of red. Brown burial accretions are present, but the surface is well preserved overall. The area of the inscription is a little browner in color and appears to have been rubbed or otherwise cleaned
The cone-shaped hollow of the socket extends in the interior to within 4 cm of the tip of the spear-foot. The interior walls show some irregularity, this is not due to slush casting wax into a mold, which would result in greater irregularity and would make it difficult to keep the interior hollow. It is possible that wax was modeled directly over a prepared core. The interior characteristics and the very thin walls at the opening support this. The point section is four-sided; the socket section is ten-sided. The transitions to the rounded areas of the exterior are very precise, and although made in the wax, was probably further cleaned up in the metal after casting. In spite of the slight alteration of the patina in the area of the inscription, the punched incisions forming the letters appear under magnification to predate the corrosion products.
