I'm going to go with Beveled St. Charles on this blade. Turner and Hester give a Texas distribution for the St. Charles Type as far East Texas with distribution of the type covering the mid-western and south-eastern USA. The Beveled St. Charles type is centered in North Carolina and becomes less common as you move westward. In Dad's notes he said that he didn't think the blade was local in origin. There were other smaller St. Charles blades in his collection but none of them were beveled. Was there a trade network between the East Coast and the Texas coast eight to nine thousand years ago ?
I've seen them listed as midwestern and south eastern points before, and thought it might be out of it's normal range. Still, during Paleo and archaic times, there had to be trade and free ranging. It's still a real beauty of a point.
WOW, what a treasure, and a story...from the broken bucket !
Googled 41FB249, lots of good info, not all related to this type, lots of data re Clovis in TX.
I got no meaningfull input on actual ID BUT....ANY typical dart point that is so oversized I personally think was exclusively meant as a BLADE ( possible exception being ceremonial )...Out of locality beveling possibly the knappers way of resharpening ? ( rather than the original configuration )..
