Fred Harvey Era-Sterling & Turquoise Bracelet-Design Attrib to Bell Trading Post

I acquired this cuff several years ago, & to date, I've only seen 2 other bracelets with the same design. Both were marked with the old Bell Trading Post "hanging sign" trademark. So, it's a mystery...is this an unmarked Bell piece, or was the design pirated by a competitor? Regardless, it's a cool & unusual design. Five rectangular stones are stacked on the center piece & are punctuated by petit point stones (that I believe to be chalk or composite turquoise) on each side. The center piece is flanked by stamped butterflies whose wings are highlighted with two rectangular stones. The split shank features scallops, thunderbirds & arrow stamped designs. For a larger wrist, the cuff measures 5 5/16" from end-to-end on the interior, plus a gap of 1 3/16". Measures 1 1/2" at center and tapers down to 1/2" at the terminals. Marked on the reverse "Sterling" and weighs in at 27.7 grams. In very good vintage condition.
