Technical Observations: The patina is a dull blackish brown. All corrosion was completely removed by stripping, and the object appears to have been repatinated after stripping. The spearhead is largely intact, although there are some surface losses and losses along the outer edges. The spearhead was cast and then hot worked. Rough finishing marks on the object could be ancient, but some appear to be from a previous cleaning.
