Pair of Wide Silver Berber Cuffs with Fish Motif

Stunning very old Berber pair of cuff bracelets bearing a Tripoli hallmark as well as another hallmark that I do not recognize. I think they are from the first part of the Twentieth Century but maybe even older. Made with high-grade silver and hand chased with Berber star and crescent and fish motifs. These bracelets' warm patina testifies to their age. They are adjustable by bending gently. The two bracelets though almost certainly made by the same hands are of slightly different lengths.  

The bracelets' inner circumference is adjustable but currently, it is 20 cm (7 3/4") including the small gap. The inner diameter is 6.5 cm (just over 2 1/2"). The width is 6.5 cm (2 5/8") for the wider one and 6 cm (2 3/8") for the shorter one. The weight of the wider bracelet is 132g and of the other bracelet is 121 g. So the combined weight is 253g.
