Hello Robert,
very good job! I have two spears of this type. By one is the shaft similar, by the second one the shaft is bulgy where the point is attached, maybe a sign of age?

I am sure that Nonoy will know it. A scond observation: both spears have a hole in the shaft to secure the tang with a "rivet" what I don't see by your spear. And both of mine have a metal socket at the end of the shaft. Maybe you find a way to blacken the point since I think they have looked originally like this. Nice spear!!
Regards,
Detlef
