Description of Physical Characteristics and Flaking Pattern:
This is a small to medium triangular expanding stem point with an elliptical cross section. The blade is primarily straight, but may be excurvate. The shoulders are horizontal to a slight upward angle. The stem is expanding with a straight to convex base. This point has a random flaking pattern.
Size Measurements: Length - 43 to 78 mm (55 mm average), Stem Length - 12 to 18 mm (16 mm average), Blade Width - 23 to 28 mm (21 mm average), Stem Width - 21 to 3278 mm (23 mm average), Thickness - 7 to 10 mm
Can you give us something for size reference please? It may be a Brewerton as 1320 pointed out, but it has more of a Woodland look to me with those large notches and it looks like one tang is missing and the base may be damaged. More views would help as well. Thanks.
