Old Bronze bangle, Asian, possibly Cambodian?

Hey Everyone, I'm looking for help to identify this item (see image). It is solid bronze, very heavy and made for a very small wrist. I thought it looked like it might be south east Asian in origin but I simply don't have enough knowledge on the subject. Any help would be appreciated. Thanks!

 

Hummm, that may well be African.
They're known for their money bracelets in bronze....
more research needed......

 

That's interesting. here are some additional images. No obvious markings on the interior.

 

If I had to guess I'd guess Ethiopian. The Nigerians work in bronze too, but the design doesn't feel West African. I may well be wrong, because this is way out of my wheelhouse.

 

Update: talked with a specialist who deals in African currency bracelets, but he said the style was unlike any he had seen and it may in fact be Islamic in origin. Still searching for a positive ID

 

good luck..

 

Hi, it could be a Bedouin bracelet (Yemen)
