Lot of 4 Vintage Native American Artifacts - 3 Flint Arrowheads (NY Provenance)

This listing includes four Native American artifacts, three of which are flint/stone arrowheads and one unique wooden piece. The three arrowheads appear to be hand-knapped flint, and they have collector’s markings on the back, indicating that they were previously cataloged. One of them is labeled "Killen’s, NF NY, #80", which may reference a site or collection from New York, liklet Niagara Falls. The fourth item is a wooden artifact, which is different from the others. I am unsure of its age or purpose, but I am including it as part of the lot. 📌 Details: ✔ Quantity: 4 total pieces ✔ Material: 3 flint/stone, 1 wood ✔ Markings: The stone pieces have collector’s notes on the back (see photos). ✔ Condition: As found – some wear, chipping, and signs of age. The wooden piece has surface wear. ✔ Provenance: The markings suggest a connection to a site in New York (NF NY), but I cannot verify authenticity. Please judge for yourself. ✔ Sold as-is. ⏎ Returns: No returns unless item is not as described. The items I sell are always in really great vintage condition, but in the interest of being conservative please remember that my items are pre-loved vintage pieces and are not necessarily "new" as you would see from a new item in store. They are preloved and will almost always show some slight wear based on the age of the item. Any actual damage will be mentioned in the listing. Thank you!
