Technical Observations: The bottom edge of the neck is apparently a cast or finished edge. The brown patina has whitish accretions and some green. The surface is not pitted, and the corrosion products show no evidence of penetrating into the metal and are not convincing as ancient. The threaded repair-plugs in the forehead and chin are modern. The patina is brownish black, while white accretions are tinted green in areas. There is no evidence of deep corrosion. Holes in the head and elsewhere are casting flaws. Whether ancient or not, the white accretions, possibly carbonates, appear to have grown due to burial or immersion rather than from manual application.
The cast is indirect, with numerous wax-drip application marks at the interior. The contours of all modeling details are mimicked on interior surfaces. The bottom edge, although irregular, appears to be a cast, finished edge. There are no indications that it is a broken edge or a failed join surface. The threaded plugs (5 mm in diameter) at the forehead and chin are not consistent with ancient manufacture.
