Ancient Projectile or Arrow Points

[sabertasche]

Hi there, it has been a very long time since I've been able to participate in the Forum and I hope I can can contribute more now that kids, jobs and life have...stabilized.

I was visiting my Dad's collection a few days ago and found these arrow points attached to some tourist-trap arrows aka "head-hunter pygmy bow and poison arrow set.

I'm pretty sure they do not belong with the cheap junk that my father bought. I'm mystified as to the culture and age, hence this post.

Over the last few years I've picked up other projectile points which I'll add to this post with the idea of forming a Forum library of points. I know there has to be a book on points of different cultures but have yet to find it. Any suggestions would be most welcome.

Back to the three points in my father's collection. One is iron and triangular in cross-section with a small tang. The others appear to be bronze, tri-lobate in section. Note that one has markings on it, the significance is not know.

Any thoughts out there as to the age, culture or authenticity of these pints?

Regards,

Greg
