Spear head identification table/guide?

[Kmaddock]

Hi
I was wondering if there is a good venue/site for identification of spear heads.

I do not like putting up threads all the time with "what spear head do you think this might be" as I like to try and participate more that just asking what I have?

I was hoping to identify a head I just purchased and started to think about such a guide, I regularly go through the archive of Lews sold page as i find there is a huge range of african knives etc that i can peruse in one go (with pictures) to try and identify what I have.

Is there a book or thread on the forum where a vast array of spears is all in one area to go through trying to find images of what I may or may not have.

When you put a search for spear head you literally get 100's of threads which are next to impossible to sort out out. My new acquisition is still alluding me from such thread perusal.

Many thanks,

Ken
