Who made this bracelet I bought in Utah? FW hallmark

Hello Paula, I have a  sterling and turquoise cuff bracelet I purchased many years ago from an “Indian” store in cedar city, Utah. If I remember right it cost somewhere around $400. Any info or input you may have would be greatly appreciated.
It has a hallmark stamp on the back of it in which I can not identify. I have pictures of the bracelet if you would like.  the hallmark reads
FW

                                                          thanks so much, Lynne

You have a beautiful classic Navajo style row bracelet. What is not typical, however, is the scroll work at the ends.
As far as the hallmark, I do not know. I have attributions to a FW hallmark where the F is stacked on top of the W. And a hallmark with periods after each initial, but none just like yours.
Perhaps someone else knows.
