Antique silver marked B I SS with swastika markings

I really do not know much about this item. It was found in the eves of an attic in a house in Milwaukee, Wisconsin, alongside a 1940's Plastic purse. The house was built in 1906 and had mainly German and Polish settlers in the area. I honestly don't know what the item is. It is too big to be a bracelet or an ankelet. It is too small to be a neckelace. The item appears to have handmade quality. The item is about 8 and a half inches long. Is silver. Has the markings B I or B 1 S S on it and two stamped swastika symbols on either side. The right swastika is off-centered. There is a little jingle piece on it.
