Huge Old Native American Navajo ? Mens Silver & Turquoise Cuff Bracelet

Beautiful old bracelet my mother picked up in the 60's at an estate sale and gave it to my father who lost it in the late 80's in a hand of poker. Fast forward to 5 years ago the person who won it from my father gave it back to me and told me to not give it back to my father to loose again :) If anyone is familiar with these old bracelets and who the maker could have been that would be cool to know. It is signed with the letter S.
