A couple good ones and a few wading river not depicted.

Love this Neville. Same rock and almost identical as in the book, however missing a tip, ugh. Also, any idea of second one guys. Brewerton?

Cannot find identical image, but near shape... brewerton Correction Perhaps...

That Neville is a heartbreaker.
Can I ask you to post a few more photos of the triangle under better lighting.
Please and thank you

The triangle you are holding is not a match for Brewerton Eared Notched, which is the page you are comparing it against. No notches at all on your triangle. Brewerton Eared Triangles can have barely perceptible ears, and one eared variants are very common in Brewerton Eared Triangles. But your triangle would not be that type, either.
