Vintage Niello Enamel Silver Filigree Bracelet Middle Eastern Look

Very pretty niello enamel and silver filigree bracelet with a Middle Eastern look. The central plaque has an engraved scene, with similar smaller scenes repeated on the flanking links. Lovely filigree and cannetille work, unmarked but nice. I'm not sure of the silver content but there are some small spots of green verdigris oxidation on back, not bad, and no other issues. Sliding pin closure. The bracelet measures 1 1/8" wide in the center and about 6" all the way around the inside and weighs 20 grams on my scale.
