Can anybody identify this artist's hallmark?

It is a sterling ring with initials WS?

Hello, the work appears to be Navajo. I felt at first that maybe the W was some flaw in the silver work and had nothing to do with the hallmark. However, everyone I showed it to believed it was part of the hallmark. With that said I could find nothing in the books or website resources I use. Good luck solving this mystery. Thanks for sharing.

Hi, found a possible match on this site has a good number of hallmarks but not the one I’m looking for, maybe this will help you.

The second one is clearly the work of Willie Shaw Navajo, the top piece could be Wilbert Secatero and just a bad strike. Hard to say for sure.
