We find this particular type of cast bronze arrowhead all over Israel dating to the Hellenistic Period, such as from the Seleucid siege of Jerusalem 134-132 BCE:
When they have a shorter tang, it looks like maybe it was deliberately clipped off rather than cast that way. That bulb, not sure what to call it, where the tang meets the base of the blade is specific to this particular type as far as I know. I've seen arrowheads like this in a report from a cite near Alexandria, but I'm curious if any of you know if they're found in other parts of the Hellenistic world. I haven't made a concerted effort yet, but I haven't noticed them in reports from elsewhere, so I thought I'd ask. Maybe you guys have seen them in museums?
