Hi folks.  It's been while hasn't it?  In spite of the Ethnographic bent that has emerged here I recall that some of you are quite versed in European material.  
I thought that I'd toss this up for consideration.
I picked this up the other day.  The form is classic and if it where shorter you would not be surprised to see it identified as a medieval arrow head.  Problem is that it is spear size (~14 ").  It has age on it but the thing that gives me pause is the tang.  For the life of me, I am not sure that I ever saw a european example of a spearhead that was tanged.  At least not one this long.  
The romantic in me says "Gosh, what a perfect example of a ballista bolt" then reality reestablishes itself.
Any thoughts?
