It is here now. Some day light pictures. There is a little damage to the pointed tip. With no idea as to when it was collected age is purely speculative but you can compare it to museum database like AMNH and NMAI. It is made of palm wood with a striking edge more like a wooden axe rather than a bludgeon club. Nicely balanced close range weapon. I would not like to be hit in the face or head with it.
