Technical Observations: The patina is a brown and black surface that looks as if it has been stripped. The edges of the spearhead show losses and deformations. The socket has been deformed and flattened, with cracking of the metal along one side. Another crack is present near the tip of the spearhead where the metal is deformed.
The spearhead was cast and then further worked, probably with annealing, to shape the tip and edges.
