Help identify large turquoise bracelet signed KS doesn't look like Kirk's

Hello and thank you for any assistance. This very large bracelet is signed KS with rays that look like whiskers extending out from the initials. The central turquoise is a huge natural and rough stone. Any guesses as to the maker if not Kirk?

This is a great bracelet. It is a traditional Navajo style with the heavy silver work and the long silver leaf. This piece predates Kirk Smith work, but I couldn’t find who the hallmark belonged to. Sadie Calvin and Mary Morgan are two names that come to mind when I see this style of work. Thank you for sharing.

Many thanks for your reply. I also recently saw a spectacular necklace by the same artist. I hope to find more information in the future.
