Now that is a war arrow!!!!
Looks very much like the arrows at the Mary Rose Museum. 1/2" ash, barrel tapered to 3/8" at nock and point. 6-8" fletch. The arrows were MASSIVE. More like short spears! The momentum must have been incredible, with that heavy an arrow loosed from a war bow.
The arrows at MRM were tapered so they were very much tip heavy, with the front barrel taper only 4-6" from the pile. Interestingly, they were not as long as I imagined... only about 28-32" overall.
