Chisel Cut FK or KF Hallmark on Vintage Chip Inlay Bracelet

Found your blog and am so glad that I did.
I have a large silver, turquoise and coral cuff bracelet that I purchased in Santa Fe a little over 40 years ago.
The bracelet is 1 5/8 inches wide and has a rather unique double badger claw design on each side.
Inside is a hallmark that is a backward F joined to a K.
I have been unable to find any reference to this hallmark and am hopeful that you or one of your readers can help.
Many thanks,

What a unique chip inlay design on your bracelet ! I’m not sure I would have seen badger paws.
I don’t recognize the hallmark so looked up chisel cut initials FK and KF and really came up empty.
So perhaps someone else might know.
I did find a Blackfoot jeweler who chisel cut his initials in a very similar fashion but I couldn’t make the combination of letters work.
But Santa Fe + chip inlay, we’d be looking for a Navajo artist anyway.
Does anyone have ideas?
