Who is the Navajo silver artist who in the 50's used the hallmark of 2 four-pronged antlers?

I am trying to find out myself. My piece (a Navajo inlay ring) has the two four pronged antlers and the initials S.B. The initials suggest that the piece is made by Shirley Baca but I can not find any reference to the symbol, nor any examples of her work.

It's Zuni master inlayer " ELLIOT QUALO " deceased.
