Large Vintage Zuni Art Handmade Sterling Multi Gem Inlay Knifewing Brooch Pin

Thanks for stopping in to see this beautifully made stone Inlay in silver Native American Art pin. I really tried to get all sorts of photos so you know just the exact age, use, size, wear, patina, wear to the stones, surface wear, nuance, look and feel from every angle. It is old and has no silver marking or signature anywhere that I can see. There is faintly what I think is a signature on the back that is scratched on maybe small in light cursive but I could be wrong. Please let me know of any questions at all!
