Help with likely native american silver bracelet mark

Hi again everyone,

I got this gem in the mail today and I'm hoping someone can help me identify the markings. The seller stated multiple times to me the bracelet was metal and not silver....but you know me I don't believe it until I see it. I was admittedly skeptical when I got it, because it is quite heavy feeling. I started with non-destructive tests, and it passed magnet test easy and performed great on the ice cube test. Finally I just decided to do an acid test and it came back nice and red even after multiple scrapes in the same spot. I haven't had any luck identifying the maker yet:

 

interesting.........the punches look NA....but repousse on heavy silver like this...i'm unfamiliar with...

 

that said...the more i look at it the more Navajo circa 1940 , it looks...

 

still, there's something about it that's throwing me off.........

 

Yeah, the thickness and weight is still odd to me. I did four very thick scrapes in the same spot for my acid test, every time bright red.

 

No idea who it is, but that almost had to be silver.
